## Summary If a lambda doesn't contain any parameters, or any parameter _tokens_ (like `*`), we can use `None` for the parameters. This feels like a better representation to me, since, e.g., what should the `TextRange` be for a non-existent set of parameters? It also allows us to remove several sites where we check if the `Parameters` is empty by seeing if it contains any arguments, so semantically, we're already trying to detect and model around this elsewhere. Changing this also fixes a number of issues with dangling comments in parameter-less lambdas, since those comments are now automatically marked as dangling on the lambda. (As-is, we were also doing something not-great whereby the lambda was responsible for formatting dangling comments on the parameters, which has been removed.) Closes https://github.com/astral-sh/ruff/issues/6646. Closes https://github.com/astral-sh/ruff/issues/6647. ## Test Plan `cargo test` |
