Minor nit: the formatting is broken in some of the examples of candidates. The first one I noticed is the last Sphinx one. Less trivial, but maybe dismissible: it says one of the authors is going to write another PEP later to add the full complement of set operators to dict. I don’t think anyone wants both + and | meaning the same thing, or wants set operators named +/&/^/- instead of |/&/^/-. But this PEP argues compellingly for + over | if we’re only adding merge. So wouldn’t you want to finish both proposals and present them at the same time, with each one explicitly invalidating the other, rather than presenting this one first with the side effect of making the second one less compelling and/or more complicated if this one gets accepted? Finally: if Mapping and MutableMapping don’t get the operators (if you’re following sequences, MutableSequence.__iadd__ exists but Sequence.__add__ doesn’t, I think?), will they be added manually to UserDict and ChainMap? (And are there any other types that need that question?) _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/2WDOMYTMG7CXCIGX4WDLZLYSR3BO4FWR/ Code of Conduct: http://python.org/psf/codeofconduct/
