While I initially found the suggestion in the PEP rather cute, that isn't enough to make it a good idea as a language addition. So, -1 for a few reasons: - the 'idiom' being replaced isn't common enough to justify dedicated syntax - the proposed syntax change isn't significantly easier to understand or significantly faster than the existing alternatives - Steven's more substantial objection that it would break the parallel between generator expressions/list comprehensions and the corresponding statements. Cheers, Nick. P.S. Some examples of past syntax changes that *were* accepted (and why): http://mail.python.org/pipermail/python-dev/2008-October/082831.html -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia --------------------------------------------------------------- _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
