Implement PEP 747: TypeForm #145033
Description
Activity
Fantastic! I should have some time within the next week to take this.
IIRC Jelle already did most of the work by implementing TypeForm inside
typing_extensions.
Heh. Nevermind. I see Jelle beat me to the punch already :)
Reacted by David Foster and Hugo van Kemenade- added a commit that references this issue
on Mar 1, 2026 #145034 is merged, and python/peps#4860 will mark it as Accepted.
Anything more to do here, or shall we close the issue?
Feature or enhancement
Proposal:
PEP-747 was just accepted. Let's implement it.
The runtime implementation should be simple and can likely be copied over from typing-extensions. In addition, we'll need docs in typing.rst and an entry in What's New in Python 3.15.
