Replace plain slice type hints with IndexSlice.

[randolf-scholz]

Trying to see what happens when we replace slice type hints with

IndexSlice: TypeAlias=slice[SupportsIndex|None, SupportsIndex|None, SupportsIndex|None]

annotations.

[brianschubert]

This seems like a good improvement to me. I imagine this would be very nice for replacing mypy's hardcoded SupportsIndex/None checks for slice indices (python/mypy#2410).

It looks like the pytype errors may be due to pytype having its own builtins stubs, which don't define slice as being generic: https://github.com/google/pytype/blob/97d949161b27259af283fc1d271f8cf056ddf9b6/pytype/stubs/builtins/builtins.pytd#L972

Closing in favor of #13008.

[randolf-scholz]

@srittau This PR is not in conflict with #13008, it is for making some annotations in the stubs more precise by replacing slice[Any, Any, Any] with more concrete types.

Thanks to #13008, one could now use slice[SupportsIndex | None] instead of an alias, since it will default to slice[SupportsIndex | None, SupportsIndex | None, SupportsIndex | None].

[randolf-scholz]

This should probably not get merged as-is. For collections.abc.Sequence and collections.abc.MutableSequence we should probably consider whether to use the weaker slice[int | None] rather than slice[SupportsIndex | None], since that ABC also only requires int for non-slice __getitem__.

[randolf-scholz]

Likewise, this would also affect operator.{getitem,setitem,delitem}

[randolf-scholz]

Hm, the only thing that sticks out to me is the aiohttp case: must implementations of Sequence support open-ended slices?

[srittau]

It looks as if aiohttp just needs to update its type hints, as the slice is just passed on to a list instance. int | None seems fine for the ABCs. (SupportsIndex | None would have been too loose.)
