Hi Mario,
The Python Steering Council today decided that we will defer consideration of PEP 648 to Python 3.11. On March 30, 2021 we sent the following feedback to you via python-dev, which began a discussion thread:
https://mail.python.org/archives/list/python-dev@python.org/message/OGYZZZ4A54RI24YEKZEPPLWU4WPRLJPE/
We on the SC extend our thanks again for the PEP, and encourage you to continue to work on this PEP for pronouncement in Python 3.11.
Cheers,
-Barry
(on behalf of the Python Steering Council)
