[sobolevn]

Summary

Hi! I am working on mypy and noticed that your project has Found 973 errors in 86 files (checked 134 source files) when checked with mypy

Reproduction Steps

1. poetry install --with=dev
2. mypy steam

Expected Results

I expect to see no errors, since mypy is a dev dependency of this project and it also has a configurations.

But, on the other hand it is not executed in the CI.
So, what is the current status of mypy in this project?

Actual Results

Found 973 errors in 86 files (checked 134 source files)

I am not going to paste all of them, because this is going to be a wall of text.

System Information

Checklist

• I have searched the issues for duplicates.
• I have shown the entire traceback, if possible.
• I have removed my username, password, shared/identity secrets and refresh/access tokens from display, if visible.

I currently use pyright as it's the checker built into vsc, and haven't touched mypy in quite a while.

I haven't been keeping up that well with the type checking in the ext.commands library but everything else should be type checkable.

Feel free to remove from mypy primer but I think it still has a fair few issues that caused regressions in pyright so might be useful.
