A dataclass of type ``enum.Enum`` does not contain the enum ``__members__`` object about astroid

I don't think so @jacobtylerwalls. That issue is basically about excluding dunders from __members__ (it isn't necessarily about data classes) while this issue is specifically about __members__ not being available at all when dataclass decorator is used. (I have a rough solution for 1730 from the past week or so :D)

Indeed @DanielNoord. Perhaps I was unclear in the comment. I meant that __members__ isn't present on the astroid representation of the class when it is decorated with dataclass. I agree that it exists on the Python class.

Pitching #1598 again as it would be nice to broaden our support for instance variables 😄

Note that this is an issue in astroid, __members__ does exist:

from dataclasses import dataclass
from enum import Enum


@dataclass
class Something(str, Enum):
	asd: str = 1  # [invalid-name]

class OtherSomething(str, Enum):
    asd: str = 1  # [invalid-name]

print(Something.__members__)
print(OtherSomething.__members__)

❯ python test.py
{'asd': <Something.asd: '1'>}
{'asd': <OtherSomething.asd: '1'>}
