+to each.
 
 ### Higher-rank types
 
-Roc uses a Rank-1 type system. Other languages, like Haskell, support Rank-2 or even arbitrary-rank (aka "Rank-N") types. Supporting higher-rank types in Roc has been discussed before, but it has several important downsides:
- 
-- It would remove principal decidable type inference. (Only Rank-1 types are compatible with principal decidable type inference; Rank-2 types are decidable but the inferred types are not principal, and Rank 3+ types are not even fully decidable.)
+Supporting higher-rank types in Roc has been discussed before, but it has several important downsides:
+
 - It would increase the complexity of the language.
 - It would make some compiler error messages more confusing (e.g. they might mention `forall` because that was the most general type that could be inferred, even if that wasn't helpful or related to the actual problem).
 - It would substantially increase the complexity of the type checker, which would necessarily slow it down.
-- Most significantly, it would make the runtime slower, because Roc compiles programs by fully specializing all function calls to their type instances (this is sometimes called monomorphization). It's unclear how we could fully specialize programs containing Rank-2 types, which means compiling programs that included Rank-2 types (or higher) would require losing specialization in general—which would substantially degrade runtime performance.
+- It would make some Roc programs run significantly more slowly. Roc compiles programs by [monomorphizing](https://en.wikipedia.org/wiki/Monomorphization), and it's unclear how we could fully monomorphize programs containing Rank-2 types. This means compiling programs which include Rank-2 types (or higher) would require sacrificing monomorphization, which would substantially degrade runtime performance.
 
 As such, the plan is for Roc to stick with Rank-1 types indefinitely.

-## Why do Roc's syntax and standard library differ from Elm's?
-
-Roc is a direct descendant of [Elm](https://elm-lang.org/). However, there are some differences between the two languages.
-
-Syntactic differences are among these. This is a feature, not a bug; if Roc had identical syntax to Elm, then it's
-predictable that people would write code that was designed to work in both languages - and would then rely on
-that being true, for example by making a package which advertised "Works in both Elm and Roc!" This in turn
-would mean that later if either language were to change its syntax in a way that didn't make sense for the other,
-the result would be broken code and sadness.
-
-So why does Roc have the specific syntax changes it does? Here are some brief explanations:
-
-- `#` instead of `--` for comments - this allows [hashbang](https://senthilnayagan.medium.com/shebang-hashbang-10966b8f28a8)s to work without needing special syntax. That isn't a use case Elm supports, but it is one Roc is designed to support.
-- `{}` instead of `()` for the unit type - Elm has both, and they can both be used as a unit type. Since `{}` has other uses in the type system, but `()` doesn't, I consider it redundant and took it out.
-- `when`...`is` instead of `case`...`of` - I predict it will be easier for beginners to pick up, because usually the way I explain `case`...`of` to beginners is by saying the words "when" and "is" out loud - e.g. "when `color` is `Red`, it runs this first branch; when `color` is `Blue`, it runs this other branch..."
-- `:` instead of `=` for record field definitions (e.g. `{ foo: bar }` where Elm syntax would be `{ foo = bar }`): I like `=` being reserved for definitions, and `:` is the most popular alternative.
-- Backpassing syntax - since Roc is designed to be used for use cases like command-line apps, shell scripts, and servers, I expect chained effects to come up a lot more often than they do in Elm. I think backpassing is nice for those use cases, similarly to how `do` notation is nice for them in Haskell.
-- Tag unions instead of Elm's custom types (aka algebraic data types). This isn't just a syntactic change; tag unions are mainly in Roc because they can facilitate errors being accumulated across chained effects, which (as noted a moment ago) I expect to be a lot more common in Roc than in Elm. If you have tag unions, you don't really need a separate language feature for algebraic data types, since closed tag unions essentially work the same way - aside from not giving you a way to selectively expose variants or define phantom types. Roc's opaque types language feature covers those use cases instead.
-- No `::` operator, or `::` pattern matching for lists. Both of these are for the same reason: an Elm `List` is a linked list, so both prepending to it and removing an element from the front are very cheap operations. In contrast, a Roc `List` is a flat array, so both prepending to it and removing an element from the front are among the most expensive operations you can possibly do with it! To get good performance, this usage pattern should be encouraged in Elm and discouraged in Roc. Since having special syntax would encourage it, it would not be good for Roc to have that syntax!
-- No `<|` operator. In Elm, I almost exclusively found myself wanting to use this in conjunction with anonymous functions (e.g. `foo <| \bar -> ...`) or conditionals (e.g. `foo <| if bar then ...`). In Roc you can do both of these without the `<|`. That means the main remaining use for `<|` is to reduce parentheses, but I tend to think `|>` is better at that (or else the parens are fine), so after the other syntactic changes, I considered `<|` an unnecessary stylistic alternative to `|>` or parens.
-- The `|>` operator passes the expression before the `|>` as the _first_ argument to the function after the `|>` instead of as the last argument. See the section on currying for details on why this works this way.
-- `:` instead of `type alias` - I like to avoid reserved keywords for terms that are desirable in userspace, so that people don't have to name things `typ` because `type` is a reserved keyword, or `clazz` because `class` is reserved. (I couldn't think of satisfactory alternatives for `as`, `when`, `is`, or `if` other than different reserved keywords. I could see an argument for `then`—and maybe even `is`—being replaced with a `->` or `=>` or something, but I don't anticipate missing either of those words much in userspace. `then` is used in JavaScript promises, but I think there are several better names for that function.)
-- No underscores in variable names - I've seen Elm beginners reflexively use `snake_case` over `camelCase` and then need to un-learn the habit after the compiler accepted it. I'd rather have the compiler give feedback that this isn't the way to do it in Roc, and suggest a camelCase alternative. I've also seen underscores used for lazy naming, e.g. `foo` and then `foo_`. If lazy naming is the goal, `foo2` is just as concise as `foo_`, but `foo3` is more concise than `foo__`. So in a way, removing `_` is a forcing function for improved laziness. (Of course, more descriptive naming would be even better.) Acronyms also use camelCase despite being capitalized in English, eg. `xmlHttpRequest` for a variable and `XmlHttpRequest` for a type. Each word starts with a capital letter, so if acronyms are only capitals it's harder to see where the words start. eg. `XMLHTTPRequest` is less clear than `XmlHttpRequest`, unless you already know the acronyms.
-- Trailing commas - I've seen people walk away (in some cases physically!) from Elm as soon as they saw the leading commas in collection literals. While I think they've made a mistake by not pushing past this aesthetic preference to give the language a chance, I also would prefer not put them in a position to make such a mistake in the first place. Secondarily, while I'm personally fine with either style, between the two I prefer the look of trailing commas.
-- The `!` unary prefix operator. I didn't want to have a `Basics` module (more on that in a moment), and without `Basics`, this would either need to be called fully-qualified (`Bool.not`) or else a module import of `Bool.{ not }` would be necessary. Both seemed less nice than supporting the `!` prefix that's common to so many widely-used languages, especially when we already have a unary prefix operator of `-` for negation (e.g. `-x`).
-- `!=` for the inequality operator (instead of Elm's `/=`) - this one pairs more naturally with the `!` prefix operator and is also very common in other languages.
-
-Roc also has a different standard library from Elm. Some of the differences come down to platforms and applications (e.g. having `Task` in Roc's standard library wouldn't make sense), but others do not. Here are some brief explanations:
-
-- No `Basics` module. I wanted to have a simple rule of "all modules in the standard library are imported by default, and so are their exposed types," and that's it. Given that I wanted the comparison operators (e.g. `<`) to work only on numbers, it ended up that having `Num` and `Bool` modules meant that almost nothing would be left for a `Basics` equivalent in Roc except `identity` and `Never`. The Roc type `[]` (empty tag union) is equivalent to `Never`, so that wasn't necessary, and I generally think that `identity` is a good concept but a sign of an incomplete API whenever its use comes up in practice. For example, instead of calling `|> List.filterMap identity` I'd rather have access to a more self-descriptive function like `|> List.dropNothings`. With `Num` and `Bool`, and without `identity` and `Never`, there was nothing left in `Basics`.
-- `Str` instead of `String` - after using the `str` type in Rust, I realized I had no issue whatsoever with the more concise name, especially since it was used in so many places (similar to `Msg` and `Cmd` in Elm) - so I decided to save a couple of letters.
-- No function composition operators - I stopped using these in Elm so long ago, at one point I forgot they were in the language! See the FAQ entry on currying for details about why.
-- No `Char`. What most people think of as a "character" is a rendered glyph. However, rendered glyphs are comprised of [grapheme clusters](https://stackoverflow.com/a/27331885), which are a variable number of Unicode code points - and there's no upper bound on how many code points there can be in a single cluster. In a world of emoji, I think this makes `Char` error-prone and it's better to have `Str` be the only first-class unit. For convenience when working with unicode code points (e.g. for performance-critical tasks like parsing), the single-quote syntax is sugar for the corresponding `U32` code point - for example, writing `'鹏'` is exactly the same as writing `40527`. Like Rust, you get a compiler error if you put something in single quotes that's not a valid [Unicode scalar value](http://www.unicode.org/glossary/#unicode_scalar_value).
-- No `Maybe`. See the "Why doesn't Roc have a `Maybe`/`Option`/`Optional` type" FAQ question
+Considering that these are the only three options, an early decision in Roc's design—not only on a technical
+level, but on a cultural level as well—was to make it clear that the plan is for Roc never to support HKP.
+The hope is that this clarity can save a lot of community members' time that would otherwise be spent on advocacy or

-In curried languages with a `|>` operator, the first expression still returns `"Hello, World!"` but the second one returns `"World!Hello, "`.

+It's unsurprising to most beginners that these work the same way; it's common for a beginner who has recently learned

-(For example, this is how `|>` works in both [F#](https://docs.microsoft.com/en-us/dotnet/fsharp/language-reference/symbol-and-operator-reference/#function-symbols-and-operators) and in [Elm](https://package.elm-lang.org/packages/elm/core/1.0.5/Basics#|%3E), both of which are curried languages. In contrast, Roc's `|>` design uses the same argument ordering as [Elixir](https://hexdocs.pm/elixir/1.14.0/Kernel.html#%7C%3E/2) and [Gleam](https://gleam.run/book/tour/functions.html#pipe-operator), neither of which is a curried language.)

-This was also a pain point I'd encountered in curried languages. I prefer the way the former example reads, but that style doesn't work with the argument order that currying encourages for higher-order functions like `List.map`. (Prior to using curried languages, I'd used [CoffeeScript](https://coffeescript.org/) in a functional style with [`_.map`](https://underscorejs.org/#map), and was disappointed to realize that I could no longer use the enjoyable style of `answer = _.map numbers (num) -> …` as I had before. In Roc, this style works.)
+The Roc version of this is nicer in that it doesn't require parentheses around the function argument. A curried language
+could theoretically adopt Roc's style of `|>` (where it pipes in the first argument instead of the last argument), but
+to get this second benefit, the language would also need to have `List.map` take the function as its second argument
+instead of the first. However, this would work against currying's one upside; it would no longer work to write
+`(List.map negate)` if the `List.map` arguments were flipped, the way they are in Roc. So currying and `|>` are unavoidably

 As a historical note, these stylistic benefits (of `|> Num.sub 1` working as expected, and being able to write `List.map numbers \num ->`) were not among the original reasons Roc did not have currying. These benefits were discovered after the decision had already been made that Roc would not be a curried language, and they served to reinforce after the fact that the decision was the right one for Roc given the language's goals.
 
 ### Currying and learning curve
 
-Prior to designing Roc, I taught a lot of beginner [Elm](https://elm-lang.org/) workshops. Sometimes at
-conferences, sometimes for [Frontend Masters](https://frontendmasters.com/courses/intro-elm/),
-sometimes for free at local coding bootcamps or meetup groups.
-In total I've spent well over 100 hours standing in front of a class, introducing the students to their
-first pure functional programming language.
+Currying leads to function signatures that look surprising to beginners. For example, in Roc, the
+[`Bool.and`](https://www.roc-lang.org/builtins/Bool#and) function has the type `Bool, Bool -> Bool`. If Roc were a
+curried language, this function would instead have the type `Bool -> Bool -> Bool`. Since no mainstream programming
+languages today are curried, anyone who knows a mainstream language and is learning their first curried language will
+require additional explanation about why function types look this way.
 
-Here was my experience teaching currying:
+This explanation is nontrivial. It requires explaining partial application, how curried functions facilitate partial
+application, how function signatures accurately reflect that they're curried, and going through examples for all of these.
+All of it builds up to the punchline that "technically, all functions in this language have a single argument," which
+some percentage of learners find interesting, and some percentage still find confusing even after all that explanation.
 
-- The only way to avoid teaching it is to refuse to explain why multi-argument functions have multiple `->`s in them. (If you don't explain it, at least one student will ask about it - and many if not all of the others will wonder.)
-- Teaching currying properly takes a solid chunk of time, because it requires explaining partial application, explaining how curried functions facilitate partial application, how function signatures accurately reflect that they're curried, and going through examples for all of these.
-- Even after doing all this, and iterating on my approach each time to try to explain it more effectively than I had the time before, I'd estimate that under 50% of the class ended up actually understanding currying. I consistently heard that in practice it only "clicked" for most people after spending significantly more time writing code with it.
-
-This is not the end of the world, especially because it's easy enough to think "okay, I still don't totally get this
-even after that explanation, but I can remember that function arguments are separated by `->` in this language
-and maybe I'll understand the rest later." (Which they almost always do, if they stick with the language.)
-Clearly currying doesn't preclude a language from being easy to learn, because Elm has currying, and Elm's learning
-curve is famously gentle.

-pointfree function composition is to never even think about using it; every other strategy leads to a worse outcome.
-
-Currying facilitates the antipattern of pointfree function composition, which I view as a downside of currying.
+Some languages place such a high value on conciseness that they would consider the conciceness upside to outweigh
+these downsides, but Roc is not one of those languages. It's considered stylistically better in Roc to write the
+second version above. Given this, since currying facilitates pointfree function composition, making Roc a curried
+language would have the downside of facilitating an antipattern in the language.
 
 Stacking up all these downsides of currying against the one upside of making certain function calls more concise,
-I concluded that it would be a mistake to have it in Roc.
+it seems clear that Roc should not be a curried language.
 
 ## Will Roc ever have linear types, dependent types, refinement types, or uniqueness types?
