I have some notes in progress for a third revision of the PEP, but I
don't think there's anything critical in them, and certainly nothing
that need delay asking for a BDFL-Delegate.
Brandt, if you are reading this[1], do you have any objection to me
applying to the Steering Council for a BDFL-delegate, or would you
prefer me to wait?
I jumped the gun a bit and discussed this proposal with the SC when we had some extra time in our meeting. The general sentiment is neutral to positive, provided the operators chosen are | and |=. The sentiment for + and += was distinctly negative. There were also some mumblings about the text of the PEP, but nothing that couldn't be fixed by some editing. I think Nick is going to send you a PR or at least a detailed critique.
There was also a question about OrderedDict. I haven't thought much about it; I suppose someone should think about what's the right thing to do here. Maybe ditto for some other common subclasses of dict, like defaultdict.
Good luck with the PEP!
