OK, I've seen this said a few times, and I have to ask: what do you mean by this? I consider myself pretty decent at Python and other languages, and I really don't get it. Especially the comparison to Java variables. Java programmers are quite used to variables which are references to objects: everything that's not a primitive type is a reference, and it's kinda hard to determine whether primitives are references or actual primitives. And many other languages have reference behavior and still call their bindings "variables", e.g. Scheme. Evan
