Remove some unneeded exceptions from mypy.ini

[nipunn1313]

Description

I removed these and found that mypy still passed (particularly since it's hard coded to target python 3.6 currently)

Checklist - did you ...

• Add a CHANGELOG entry if necessary? (not needed)
• Add / update tests if necessary? (not needed)
• Add new / update outdated documentation? (not needed)

Looks good but you merge conflicted yourself :)

Huh, I wonder what's different this time as Łukasz had one hell of a ride trying to silence mypy for _unicodefun when we first added support for Click 8+.

[nipunn1313]

My best guess is that it's because mypy.ini hard codes python 3.6?
It's also possible newer version of mypy changed something.
Doesn't feel super critical to track down.

if only community/community#4477 - it were possible to avoid this. I prefer to make two CRs instead of one if the changes are independent. I consider it a shortcoming of github that I can't pre-handle this by stacking them.

Yeah if only. I'm working on getting black compiled with mypyc and it's failing because of the exception that we previously silenced: https://github.com/ichard26/black-mypyc-wheels/runs/4040805225?check_suite_focus=true#step:5:197

*sigh*

[nipunn1313]

Dah!

Probably something like would this allow you to handle it w/o ignoring unused ignores broadly all the way across black/__init__.py.

- for module in (core, _unicodefun):
+ for module in cast(Any, (core, _unicodefun)):

^ I just confirmed this works

Put up #2573 in case you want it

[ichard26]

Did you check with mypyc? I ask that because it's rather strict (makes sense as a compiler) so even mypy passing code might not work.

I can check regardless.

[nipunn1313]

I did not check it. Good point about its strictness.

I suspect the old ignores were not needed w/ mypyc because the library imports were probably coming in as Any rather than types.ModuleType for mypyc.
