Based on feedback from the latest discussion thread, I hope @serhiy-storchaka might sponsor this.

(Alternative formatting with mathjax)

N.B. I did local builds with the default sphinx config and it seems, that "math" directives are rendered odd with the "maths_to_html". In particular, equation numbering is lost (though, references to equations are kept). Any way to fixing this without replacing "math" with something else? CC @AA-Turner
Locally I've something like this:

Please review PEP 1.

The general order of things:

  1. Open a discussion to see if there is consensus for this idea. This is also to save you time in case the idea is rejected.
  2. During the discussion, find a sponsor.
  3. Work with your sponsor, and when they think the PEP is ready for submission, then open the PR.
  4. A PEP number is assigned by a PEP editor after the sponsor has confirmed their sponsorship.

Therefore please don't write and submit a PEP with just a hope someone will sponsor. This should be arranged beforehand.

@hugovk, may I reserve some number and set CODEOWNERS?

Yes, you may use 812. Thanks!

@serhiy-storchaka, have you changed your mind on support of this PEP?

If not, what's left here to do?

OK, I'm closing this. I guess, @serhiy-storchaka not willing to support this proposal anymore.

@hugovk, thanks for review.

I'm reopened this, as sponsorship wasn't revoked.

Lets wait for Serhiy replay. If he changed his mind on supporting this, we could recycle 812 to the free pool of PEP numbers.
