trio has a parameter defaulted to
Noneand trio-stubs doesn't have that parameter hinted as
In this context, would the problem be in trio, or in trio-stubs?
defaultswould lose its typing when used in inherited class? This only applies to an attribute with the name
=Noneand the stubs have
: trio.abc.Clock = .... seems like it would be good to have some tool or another able to find this discrepancy.

Any. I'm currently running into a snag where I don't know how to deal with a
NewTypethat I defined - what I'm trying to do results in a mypy error. Please find below a minimal reproduction of the problem. Does anyone have any advice or am I forced to leave it as
# test.py from dataclasses import dataclass from typing import NewType A = NewType("A", str) @dataclass class Test: a: A
# stubgen'd test.pyi from typing import Any A: Any class Test: a: A def __init__(self, a: Any) -> None: ...
# trying to remove 'Any' as much as possible from typing import Type A: Type[str] class Test: a: A # mypy error: "test.A" is not valid as a type def __init__(self, a: A) -> None: ... # mypy error: "test.A" is not valid as a type
