If someone comes with a "pythonic" way to lift restrictions on lambda, that could be something for debate, but so far this is just about uglifying it, and creating a new syntax matching exactly what exists today. Moreover I'd like to remind people so much worried about expressiveness in less and less characters that Lambda is much less needed in Python than in similar languages due to the existence of the comprehensions and generator expression constructs. The energy spent here could be focused instead on having an equivalent of comprehensions for "reduce", for example. > -- > ~Ethan~ > _______________________________________________ > 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/IU7DEE5WZFWDKFDPUZAYCV5DPGFGSAJK/ > Code of Conduct: http://python.org/psf/codeofconduct/ >
