iPython is just another application;   references to objects are handled by
Python.  It's about what assumptions you want to make about the environment
in which you will operate.

Here is not-iPython, showing same kind of thng.   If you have complete
control of execution envirioment, then you can make predictions about
references that may be created; if not, you cannot.

$ python
Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)]
on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> class foo(dict):
...   pass
...
>>> f=foo
>>> f
<class '__main__.foo'>
>>> b=f
>>> [k for k,v in vars().items() if v is foo]
['b', 'f', 'foo']
>>>
