They wouldn't be as transparent as references in C++,
which you just assign to like any other variable.

That works because C++ makes a distinction between
initialisation and assignment. It's not so easy to
separate those in Python.

That would be like pointers in C that you have
to explicitly dereference. I'm not sure whether
C could be described as having "first class
variables", though.

If transparency is not required, you can easily
create wrapper objects in Python that refer
to an attribute or element of an object.
