Update: PEP 655 was submitted to python-dev on Jan 29 (1 month ago) [1] and to Discourse/PEPs on Feb 20 (3 days ago) [2] for core dev review, here on this email thread in typing-sig. I have since then received 2 items of feedback, one of which is still pending integration. [3] [4] **Please send me any further feedback by the end of this weekend, Sun Feb 27.** After that point I plan to submit the PEP to the Steering Council for final review as per PEP 1 [5]. -- David Foster | Seattle, WA, USA Contributor to TypedDict support for mypy [1]: https://mail.python.org/archives/list/python-dev@python.org/message/C7QCZ5J2...
