This comment states that this class fails at runtime, but that isn't true:
```pycon
>>> from typing import *
>>> T_co = TypeVar("T_co")
>>> class Proto2(Protocol[T_co], Generic[T_co]): ...
...
>>>
```
The comment should instead quote the spec [here](https://typing.python.org/en/latest/spec/protocol.html#generic-protocols), which states that type checkers should consider it an error (even though it does not fail at runtime)
