- The attrs.field converter parameter does not support higher-order functions.
- stubtest: Add a `--ignore-keyword-only` argument
- Descriptors misbehave with `NoReturn`/`Never`, with `@overload`s, etc.
- False negative with property and decorator
- Optional[TypeVar] does not preserve type of TypeVar when given Union type
