It is the PEP, looking to force change to the language, to prove its point rather than dismiss statements of its detractors. > > The "not readable" objection has been made, extremely vehemently, > against nearly all major syntax changes to Python: I don't count myself as usually against change. I applaud the move to Python 3, I use all of the language features you mention at times; many in my Rosetta Code task examples; but this change opens the door to a class of bug that will take care to avoid and which I remember cutting my C coding to get away from. The PEP fails to adequately address the concerns of "us naysayers" For example; if someone were to find out that "assignment expressions were faster", then you would be hard pressed to stop their over-use. As soon as someone assigns to a name and uses that same name in the one expression, you need a better grasp of the order of expression evaluation to read it. hat is best avoided, in my subjective, personal, view. > -- > Steve With respect, but in disagreement - Paddy. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
