Yep. Rubyphiles would probably define these 3 methods in a "module" Iterable and "mix" it in their brand new container classes. These classes then automatically have list, sorted and join *as methods*. Guess you could use this kind of trick in Python if you can live with heavy *and* implicit surgery of the inheritance chain ;) Cheers, SB -- http://mail.python.org/mailman/listinfo/python-list
