Actually, there's a fairly huge difference. All you've done is create
a thing which can set a global... you don't have any way to pass
pointers around, like you can in C. (And that's even without getting
into pointer *arithmetic*.) You have to construct a dedicated "thing"
in your source code for every pointer you want to be able to work
with. And if you try to make a single generic "Ampersand" class, what
you'll find is that you're working with namespaces, not addresses. So
Python's name-binding model really is fundamentally different from C's
stuff-in-memory model.
