Pylint hangs when running on a module that has type annotations from returns
See original GitHub issueI’ve noticed pylint is hanging (vscode’s python plugin started to consume 100% CPU) when trying to lint a module that has type annotations from returns library.
Consider the following test.py:
from returns.maybe import Maybe, Some
x: Maybe[int] = Some(1)
Running pylint test.py will hang forever.
Not sure if the problem is with returns or pylint itself (or maybe something with my local setup, tried both with my regular pylint config and without it though). Didn’t spend much time debugging it, but sometimes I noticed it hangs in astroid.decorators.raise_if_nothing_inferred generator. Does anyone experience the same?
python: 3.7.9, 3.9.0
pylint: 2.6.0
astroid: 2.4.2
returns: 0.15.0

Please, report this on pylints repo! And post an issue number here. 👍
I can help pylint’s team, but there’s nothing we can do from our side.
