bpo-42195: Disallow isinstance/issubclass for subclasses of genericaliases in Union (GH-24059) Previously this didn't raise an error. Now it will: ```python from collections.abc import Callable isinstance(int, list | Callable[..., str]) ``` Also added tests in Union since there were previously none for stuff like ``isinstance(list, list | list[int])`` either. Backport to 3.9 not required. Automerge-Triggered-By: GH:gvanrossum
