You are right, I didn't think of this ambiguity w.r.t. to the start of the expression. While `lambda` clearly marks where the lambda body starts, `?` doesn't do this. Actually the above example could also be translated to `lambda x: members.sort(key=(x[1], x[0]))` (which doesn't make sense, of course, but it's valid syntax). _______________________________________________ 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/6NGYVZZP7K3ZEHETHKU4AVDHA24QMICY/ Code of Conduct: http://python.org/psf/codeofconduct/
