Thanks for explaining. I was trying to do something like
@dataclass
class A:
x: ClassVar = set()
and thanks to you I know it should be
@dataclass
class A:
x: ClassVar[Set] = set()
If you are looking for improved error message, it's probably should be somehow connected to not proper usage of annotation. I've ended with default_factory because x: ClassVar = set() wasn't working and there was no error with default_factory and without slots.
