New submission from Gregory Beauregard <[email protected]>:
```
class C:
a: "ClassVar"
get_type_hints(C, globals()) # TypeError: Plain typing.ClassVar is not valid
as type argument
```
A stringified lone ClassVar raises at runtime, but this pattern is tested for
in dataclasses unit tests and used in the wild. The PEP is not clear that it
should or should not be used with arguments, and it works fine when not
stringified.
The fix for this is trivial and I can submit a patch if there's agreement.
