It's quite common to see documentation warn API users only to call a function with keyword arguments, so there's definitely a desire. But certainly with the already-agreed-upon keywords-after-*args it would be easy to implement this with one assert, where now it is quite tedious. I don't know if there's an advantage to presenting a signature that accurately describes the function; it can never *really* be accurate in all cases, as there can be all sorts of constraints that are impossible to represent in the signature (like mutually exclusive keyword arguments). But then by putting in *args to constrain arguments to keywords, you formally represent the keyword constraint while adding a very inaccurate representation of the function signature for positional arguments. -- Ian Bicking / [EMAIL PROTECTED] / http://blog.ianbicking.org _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
