```
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. |
