+            Intrinsics are never intended to be stable directly, but intrinsics are often
+            exported in some sort of stable manner. Prefer using the stable interfaces to
+            the intrinsic directly when you can.

-                Currently the only stable way to create a `Box` is via the `Box::new` method.
-                Also it is not possible in stable Rust to destructure a `Box` in a match
-                pattern. The unstable `box` keyword can be used to create a `Box`. An example
-                usage would be:
+            These are imported as if they were FFI functions, with the special
+            `rust-intrinsic` ABI. For example, if one was in a freestanding
+            context, but wished to be able to `transmute` between types, and
+            perform efficient pointer arithmetic, one would import those functions
+            via a declaration like
 
-                ```rust
-                #![feature(box_syntax)]
+            ```rust
+            #![feature(intrinsics)]
+            #![allow(internal_features)]
+            # fn main() {}
 
-                fn main() {
-                    let b = box 5;
-                }
-                ```
+            extern "rust-intrinsic" {
+                fn transmute<T, U>(x: T) -> U;
 
-            "##]],
+                fn arith_offset<T>(dst: *const T, offset: isize) -> *const T;
+            }
+            ```
+
+            As with any other FFI functions, these are always `unsafe` to call.
