Late to the game, I like the proposal a lot but have a couple of questions about it.
Why the need for strictness of type for the operator? I get that it's analogous with the behavior for `list`, but I guess I'm also not sure why that should be strict. As a compromise in regard to strictness, what it anything that is a `Mapping` or has `.asdict()` could be added using the operator but only those kinds of thing? Also, why was subtraction dropped? It seems to me the ability to subtract an iterable of keys makes a lot of sense — or maybe that should be a separate PEP? _______________________________________________ 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/E5UTQONRQULDHMD2XXHLUNI4SS267CXL/ Code of Conduct: http://python.org/psf/codeofconduct/
