Having path descend from str/unicode is extremely useful since I can then pass a path object to any function someone else wrote without having to worry about whether they were checking for basestring. I think there is a widely used pattern of accepting either a basestring[1] or a file-like object as a function argument, and using isinstance() to figure out which it is. What do you gain from removing these methods? A smaller dir()? [1] Probably str in actuality. -- Michael Hoffman -- http://mail.python.org/mailman/listinfo/python-list
