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.
