[issue45384] Accept Final as indicating ClassVar for dataclass

[Gregory Beauregard]

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 email to the PEP authors since probably whatever happens the PEP needs a clarification anyway.
