Are people who never find 2-arg next going to find itertools.first? I think most people who use itertools regularly enough to look there are people who already know 2-arg next (and also, mostly people who are “thinking functionally”, for that matter). Other people will discover it if someone points them there on -list or on StackOverflow or as student help or whatever, but they can already discover 2-arg next the same ways. In fact, what they’re probably going to find on StackOverflow is an answer all about 2-arg next, with a little edited-in footnote or comment saying “if you’re using the upcoming 3.9, you can use first instead of next and leave out the call to iter”. _______________________________________________ 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/Z2BRQHLBWXF2GL25JG7SL56UORFENIHI/ Code of Conduct: http://python.org/psf/codeofconduct/
