F821 on a Literal type that isn't directly imported by the current module #2105
Description
We're getting a F821 on a Literal type over in pypa/cibuildwheel#1405 . I've isolated this to the following-
Two files are needed-
script.py
from __future__ import annotations
from script_typing import Literal
testing_archs: list[Literal["x86_64", "arm64"]]
testing_archs = ['x86_64']
print(testing_archs)script_typing.py
import sys
if sys.version_info < (3, 8):
from typing_extensions import Literal
else:
from typing import LiteralHere's what happens:
$ ruff --isolated --fix script.py
script.py:5:29: F821 Undefined name `x86_64`
script.py:5:39: F821 Undefined name `arm64`
Found 2 error(s).This happens without any pyproject.toml configuration
Version: ruff 0.0.230.
p.s. ruff seems pretty incredible! the speed 🤯
