Closes #2148

I have not updated the readme as there is no strict reference to the supported mypy version, and it looks like the changelog contains release info, so I didn't touch that one either.

All the checks passed, even though I had to add an ignore flag in a function that was using some strange trait-based property access.

I used a solution very similar to the one used in typeddjango/django-stubs#2670 but I get the version info using importlib instead of the string in the module.

This is strange. I haven't seen these issues on my side. 🤔

You updated

name = "wemake-python-styleguide"
version = "1.1.0"

Let's pin it to 1.0 for now :)

Oh? I didn't notice. I think I might have just ran poetry update -U to get the latest version of Mypy and that updated everything in the lock file. Should I change the entry in pyproject.toml to limit the version to 1.0?

[sobolevn]

yes, please :)

Rebased against master and pinned version
