Handle ignored mypy errors in ``pandas/core/arraylike.py``.
This pull request is stale because it has been open for thirty days with no activity. Please update or respond to this comment if you're still interested in working on this. @ivanovmg if you can merge master and update Thanks @ivanovmg I think the idea is to remove the ignores as they can be seen as a sort of TODO. adding the comment imo does not move this forward.

I think if you revert 8b8348621799ef64f1da2434c0e0f1f6f6874064. we can then just merge as was. see https://github.com/pandas-dev/pandas/pull/39257#discussion_r574442092 looks like @simonjayhawkins 's concerns have been addressed, so LGTM thanks @ivanovmg
