- Exhaustiveness checking false positive regression in 1.10
- Feature Request: a secondary error for overrides based on compatibility
- no error when using generic in `except` block
- Set and Dict generalizing the type unnecessarily
- Unpacking doesn't do proper type narrowing
- Dataclasses: `No overload variant of "asdict" matches argument type "Self" [call-overload]` when deciding decorator conditionally
