Use of deprecated type hints - PEP 585

[jeertmans]

Hello,

I am a frequent user of your library, but I also like to enforce good type hints, using type checkers like beartype.

However, when using types from your library, it appears that some of them use deprecated type hints from the built-in typing module, like typing.Iterator that has been moved to collections.abc.Iterator.

While this is not an issue at the moment (except that beartype complains about it, see https://beartype.readthedocs.io/en/latest/api_roar/#pep-585-deprecations), this will eventually become one when Python 3.14 will come out (in ~ 1 year I guess).

Could you consider updating the type hint to make your library future-compatible (at least to some extents)? Of course, I can help with this and make a PR.

Thanks for your work!
