[issue45384] Accept Final as indicating ClassVar for dataclass

Carl Meyer added the comment: Good idea to check with the PEP authors. I don’t think allowing both ClassVar and Final in dataclasses requires general intersection types. Neither ClassVar nor Final are real types; they aren’t part of the type of the value. They are more like special

[issue45384] Accept Final as indicating ClassVar for dataclass

Gregory Beauregard added the comment: Thanks for the feedback Carl. Your proposed nesting PEP change is not possible: ClassVar[Final[int]] isn't valid because Final[int] isn't a type. As far as I know this would need type intersections to be possible. I'm going to try sending a one-off
