Descrizione

I'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`:
```python
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
```
