Thanks for the help, @hugovk.

Some little nits

[msarahan]

Anything else needed here, @hugovk ? Barry explained to me that we should try to get this merged, then continue to revise the content according to discussions on discourse.

[hugovk]

Yep, if no-one has any comments let's merge! @warsaw: any final review suggestions, or good to merge?

@msarahan Once merged, please open a new discussion topic, then open a quick PR to put that link under Discussions-To, and also append it to Post-History (re: https://peps.python.org/pep-0001/#discussing-a-pep)

[msarahan]

Is a new discussion topic necessary? I read that part of PEP 1, but I think the thread at https://discuss.python.org/t/pep-766-handling-multiple-indexes-index-priority/71589 fulfills the purpose described by PEP 1 of being a canonical discussion place, and the thread isn't terribly long (yet?)

I feel like starting a new topic would only spread the existing discussion around more places.

[warsaw]

Good from my side, thanks @hugovk. I'll go ahead and merge.

Yeah, this is why PEP 1 says to open the canonical discussion after merging the PR and getting the proper PEP URL.

Fair enough, please could you edit the top post to link to https://peps.python.org/pep-0766/ and not just this PR?
