To Reproduce

from __future__ import annotations

import attrs


@attrs.define
class X:
    x: int


attrs.fields(X) # fine


def func(klass: type[attrs.AttrsInstance]) -> None:
    fields = attrs.fields(klass) # error
    print(fields)


func(X) # fine

Expected Behavior

Success: no issues found in 1 source file

Actual Behavior

% mypy x.py
