Python already allows positional arguments after keyword arguments: py> sorted(reverse=True, *([1, 4, 2, 3],)) [4, 3, 2, 1] > And quoting your next message: > > > All else being equal, we should prefer the syntax that doesn't rule > > out future development. > > I don't think all else is equal.

There is a qualitative difference between: "Your proposal will rule out this specific thing and should be weighed up in light of that" and "Your proposal could rule out some unknown thing that nobody has thought of, so it should be rejected!" I have an actual, concrete possible enhancement in mind: relaxing the restriction on parameter order. Do you have an actual, concrete future enhancement in mind that relaxing the restriction would conflict with? -- Steven _______________________________________________ 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/UB6B6OQUEEFATF5INKESFQ5QECE4ZNZZ/ Code of Conduct: http://python.org/psf/codeofconduct/
