Add a way to ignore type: ignore, disabled error codes #13201
Description
Feature
My goal is to check all the ignored inline mypy errors/warnings
Pitch
People often added inline comment # type: ignore to ignore mypy error for a specific line, but it's difficult to trace for other developers, or for audit purpose. Now I would like to have something similar to flake8 --disable-noqa, which show all the mypy errors/warnings regardless of these inline ignores.
