gh-105578: Raise `DeprecationWarning` on `typing.AnyStr` usage by sobolevn · Pull Request #150190 · python/cpython

Thanks! Wow, that came around quickly.

I had to think this through again, but I think this is correct: this is a deprecation for Python 3.16, which will become stable in autumn 2027, around the same time that Python 3.11 goes end-of-life. That means that the deprecation warnings will start to be emitted at basically the same time that the lowest non-EOL Python version is Python 3.12 -- and Python 3.12 is the first version in which users can use PEP-695 syntax
