As the one who made that accusation, my objection was specifically to the word "always" - which was emphasized - and which is something that I don't believe is actually a component of the test that is normally applied. His words, specifically, were "a compelling argument needs to be presented that the new spelling is *always* preferable to the existing ones" List comprehensions themselves aren't even always preferable to loops. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
