@ Editors and Team - There has been an initial discussion which went off track. I am inclined to open up a new one, or should the old one be continued?

Hello, PEPs need a sponsor before opening and assigning a PEP number. Please can you find a core dev sponsor via the discussion thread, and we can re-open then?

See https://peps.python.org/pep-0001/#submitting-a-pep

Thanks.

[JelleZijlstra]

I can sponsor this PEP. I think PEP 821 is taken by now but @Daraan if you renumber it to the latest available number, we can merge it.

[hugovk]

823 is next, please update the files to use this.

[hugovk]

Actually, 821 isn't used, please keep it :)

[hugovk]

Please also wrap to ~80 columns.

[Daraan]

Thank you very much @JelleZijlstra for the sponsorship! Thank you very much @hugovk for the first review. I've applied your suggestions and additional minor changes.

@JelleZijlstra Please review and merge when you're happy with it :)
