@gvanrossum @ilevkivskyi:

• Would you mind to review this change?
• Is it ok to rename the private typing._PROTO_WHITELIST variable?
• Should we keep an alias (_PROTO_WHITELIST = _PROTO_ALLOWLIST) during 1 or 2 releases?
• Should I document this change change in a NEWS entry?

[vstinner]

FYI I also renamed one test_typing test in commit 0ee0b29.

I prefer not to do this. I find it linguistically awkward, and reading the history of “blacklist” on Wikipedia I don’t see any connection with racism. https://en.m.wikipedia.org/wiki/Blacklisting

Yes, the term is not racist. It's more subtle. The negative co-notation of black is death by a thousand paper cuts. The great Muhammad Ali explained this in multiple interviews, e.g. https://www.youtube.com/watch?v=7eXdt1eGgCA

Then someone else can approve this. I hope you understand.
