What other languages use the same data model as Python?

The flaw of this model, and I am not discounting its merits, just
pointing out that it isn't perfect, is that it creates the illusion
that references are boxes (objects) just like data objects, leading
the reader to think that we could have a reference to a reference.
If they are all boxes, by can't we make reference thereto?
