This is a great PEP. Just recently I needed this and was surprised that
nothing of the sort had been implemented yet (I looked for quite some
time).
I have one suggestion: Wouldn't it be useful for these operators to also
accept sets (functionally acting like a dict with None for all values)?
This would make it very elegant to 'normalize' dicts by pruning (dict &
set) or padding (set | dict) dictionaries. I would find this useful for
efficient data sanitation purposes, as when processing input from web
forms.

Thanks Brandt (and Steven of course)! If there are no objections by
next week I'll recommend this to the Steering Council for acceptance.
In the meantime, I am wondering about the reference implementation --
is it suitable to submit as a PR? Or is it a toy written in pure
Python? (I found it a little tricky to follow your branch.)

Steven D'Aprano and I have pushed a third draft of PEP 584:
https://www.python.org/dev/peps/pep-0584/ [1]
The accompanying reference implementation is on GitHub:
https://github.com/brandtbucher/cpython/tree/addiction [2]
For those who have been following the discussions over the past
year on python-ideas, this new draft does not contain much
additional content; the most notable difference is that the choice
of operator has been changed from + to |. The rest of the revisions
are mostly reformatting and reorganizing the information to bring
the document in line with PEP standards.
Please let us know what you think – we'd love to hear any *new*
feedback that hasn't yet been addressed in the PEP or the related
discussions it links to!
Thanks!
Brandt
