I just realized that this would be silly, complex, etc.

Say you could (as another poster mentioned) do something like
this:

>>> a = 5
>>> b = ref_to(5)
>>> a = 3
>>> print b
3

This would require a new built-in probably, and any time you
(accidentally?) did 'b = c', then you'd lose that reference,
but...  hmm, I wonder if it'd be handy.

Probably not enough to justify the expense.  :)
