this actually is starting to collide with the other places Any is used, which is getting annoying, but you have to commit incremental progress at some time...

this actually did not matter for the code, I guess. The only reason to change it was because mypy was complaining because mypy doesn't allow redefinition that way (at least with these settings). But instead of beating mypy into doing what I want, I just made the types follow the error message here.

This attempts to get at mypy/config_parser.py:620: error: Incompatible types in assignment (expression has type tuple[int, int], variable has type Optional[bool]) [assignment] however, I think this leaves v undefined in the else path, which is bad

According to mypy_primer, this change doesn't affect type check results on a corpus of open source code. ✅ |

Oh, that's funny. Now the only failing tests are the tests we put in to check the values the other way... Makes sense, I suppose. |

This pull request removes the Anys (and the ignore) from mypy/config_parser.py, fixing #19566. This is a refactor, but it also ensures that the class of bugs (unfriendly error messages) triggered by runtime type errors do not occur here further.
