What I am argueing is that it is very natural for python programmers to assume that keyword arguments will work if they see a signature. IMO if a python programmer sees something like: abs(x) It is very natural to envision a corresponding def statement like: def abs(x): and a python function written like this will work if called as follows: abs(x=5) IMO this is a very natural thought process for a python programmer. So a python programmer seeing the first will tend to expect that last call to work. Now frederic claims that the general rule is different. Now I'm perfectly happy to accept that those who write the documentation do so based aacording to the rule frederic stated (you can't/shouldn't use a parameter as a keyword argument unless explictly stated in the documentation), but that doesn't contradict that readers may have different expectations. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
