Description
Feature
This PR introduces a new check for mypy: we now can find incompatible __post_init__ methods in @dataclasses: https://github.com/python/mypy/pull/15503/files#diff-f96a2d6138bc6cdf2a07c4d37f6071cc25c1631afc107e277a28d5b59fc0ef04R1048-R1050
But, the thing is that for now we are using a direct call to dataclasses internal plugin, because there are no ways to do it otherwise.
Pitch
Let's discuss possible options we have to introduce a new API that can solve this problem.
