[iritkatriel]

As proposed by @JeffersGlass.

• Change is either:
  • To a Draft PEP
  • To an Accepted or Final PEP, with Steering Council approval
  • To fix an editorial issue (markup, typo, link, header, etc)
• PR title prefixed with PEP number (e.g. PEP 123: Summary of changes)

@mnoori1201 Hello, it's not very helpful to approve PRs which have already been merged (this and several others), especially when done without any comments. Thanks.
