SC Acceptance: PEP 646 -- Variadic Generics
Hello Mark, Matthew, Pradeep, Vincent, and Guido, The Python Steering Council discussed the latest version of PEP 646 (Variadic Generics) at our last meeting, and have unanimously decided to accept the PEP. Congratulations! We want to specifically mention that we appreciate the way you called out the Python grammar changes required by the typing features you proposed. As we’ve said before, the Steering Council strongly believes that the typing language and the “general” Python programming language should remain aligned, so the implications of syntax change proposed in the PEP for typing needed to be addressed for non-typed Python as well. The PEP explains this change well, and does a good job of justifying the semantics and usefulness of the change for non-type related purposes. Please feel free to change the PEP status to Accepted, and to merge your changes to Python 3.11 at your convenience. With our appreciation, -Barry (on behalf of the Python Steering Council)

Hello Mark, Matthew, Pradeep, Vincent, and Guido, The 2022 Python Steering Council discussed the updated PEP 646 -- Variadic Generics, and decided to accept the PEP again, with the following note: The details around multiple unpackings in a type expression aren't specified precisely. This gives individual type checkers some leeway, but can be tightened in future PEPs. Please feel free to change the PEP status to Accepted and add the note to it, and merge your changes to Python 3.11. As Barry mentioned previously, we appreciate justifying the changes for non-typed Python as well. Thank you for your patience as we set up the new SC, and happy typing! - Petr (on behalf of the Python Steering Council)
Fantastic, Petr! Thanks for letting us know - and thank you once again for your patience with our last-minute changes! We'll go ahead and mark the PEP as accepted, and merge our CPython implementation soon. On Wed, 19 Jan 2022 at 08:34, Petr Viktorin <encukou@gmail.com> wrote:
