Official `typing_extensions 4.13.0` release begging :beaver:

[leycec]

@JelleZijlstra, @brianschubert, @Daraan, @AlexWaygood, @hauntsaninja: Merry almost-Christmas, wonderful fellow Typonistas. You may know me from such hybrid runtime-static type-checkers as @beartype. On behalf of @beartype and our upcoming beartype 0.20.0 release, I shall now proceed to beg ineffectually for an official typing_extensions 4.13.0 release.

@beartype internally depends on the unreleased PEP 747-compliant typing.TypeForm[...] type hint factory, because it seemed like a good idea at the time. It now seems like a bad idea and I regret my life choices. Using TypeForm is kinda complicated by the lack of a concomitant backport in typing_extensions... or any support whatsoever from anyone anywhere.

I've temporarily hacked around this omission via some kludgy if typing.TYPE_CHECKING: ugliness in the @beartype codebase, which absolutely doesn't pass inspection. I'm unconvinced my kludges will actually hold up to scrutiny by end users in the absence of a typing_extensions release officially backporting TypeForm. I'm shook.

The next stable release of @beartype is thus blocked by the next stable release of typing_extensions. This is my fault, of course. Let this be a lesson to never depend on anyone. I hate release begging, but I am now release begging. It's been literally six months since the last stable release of typing_extensions, which is almost as bad as the @beartype release schedule. Which is to say... it's bad. Things don't get worse than the @beartype release schedule. 🤣

In Conclusion, May typing_extensions Endure Forever

Thanks so much for all the amazing typing backports over these many years, y'all! May Python win all the glory in 2025.

Yes, we should release soon. Note that by our policy, we'll have at least a one-week wait between a release candidate and final release.

I still want to add PEP 728 support too but haven't gotten around to it yet.

Note that typeshed will also need a TypeForm in typing_extensions.pyi

Indeed, this is the @beartype release policy as well: safety first. 🦺 🥽

Thanks for the prompt attention, y'all. I see that the future of QA is in excellent hands.
