The root of the issue is that I started using `visit_annotation` for these bounds. So we'd queue up the bound in the list of deferred type parameters, then when visiting, we'd further queue it up in the list of deferred type annotations... Which we'd then never visit, since deferred type annotations are visited _before_ deferred type parameters. Anyway, the better solution here is to use a dedicated flag for these, since they have slightly different behavior than type annotations. I've also fixed what I _think_ is a bug whereby we previously failed to resolve `Callable` in: ```python type RecordCallback[R: Record] = Callable[[R], None] from collections.abc import Callable ``` IIUC, the values in type aliases should be evaluated lazily, like type parameters. Closes https://github.com/astral-sh/ruff/issues/8017. ## Test Plan `cargo test` |
