Related to python/typing#1425 ?
Daraan commented on Nov 25, 2025
Yes, or rather the follow up python/cpython#133602.
The follow up on typing_extensions is #699, which is not yet in a release.

Even with #699 applied, test_alias_names_still_exist fails

Thank you, you are right. Adjusting __all__ is not enough we need to also adjust _typing_names for the tests. I've added #723 and tested with 3.15.0a4 for the tests to pass.
