While I think there's some promise in this approach, I struggle with Any annotated datetimes. The __sub__ overloads (for example), derive a return type of Any, probably because mypy is merging the timedelta and NoReturn annotations of multiple annotations. Does anyone have an idea how to work around this?

Apr 29 '24 15:04 srittau

I don't have much to add except to say that having this will be truly great, my code is littered with "aware"/"not aware" comments which really should be in the type, so I hope you can get it to work. (I haven't been bothered with it enough to use something like DataType yet).

I am curious about two things:

Why default TzInfoT to Any instead of tzinfo | None?
Why are the overloads needed? I guess typecheckers don't know the type of default values so they don't see that fromtimestamp(123) is the same as fromtimestamp(123, tz=None) and so can't infer TzInfoT=None?

@bluetech

Why default TzInfoT to Any instead of tzinfo | None?

It tried both, but both didn't work. tzinfo | None is also my preferred default, but I hoped that Any would have less problems when it didn't.

Why are the overloads needed? I guess typecheckers don't know the type of default values so they don't see that fromtimestamp(123) is the same as fromtimestamp(123, tz=None) and so can't infer TzInfoT=None?

Exactly.
