Huh? The interface could continue to be (map ...). Python's for statement relies on the fact that python is mostly object oriented and many of the predefined types have an iterator interface. Lisp lists and vectors currently aren't objects and very few of the predefined types have an iterator interface. It's easy enough to get around the lack of objectness and add the equivalent of an iterator iterface, in either language. The fact that lisp folks haven't bothered suggests that this isn't a big enough issue. The difference is that lisp users can easily define python-like for while python folks have to wait for the implementation. Syntax matters. -- http://mail.python.org/mailman/listinfo/python-list
