Yes and no.  Officially, there is no way.  There are, however, hacks
that may or may not work.  For example, there is sys.makeref from
mxTools (http://www.egenix.com/files/python/mxTools.html).  Do note
the warnings on that page:

"""
USE WITH CARE: this is an expert-only function since it can cause
instant core dumps and many other strange things -- even ruin your
system if you don't know what you're doing !

SECURITY WARNING: This function can provide you with access to objects
that are otherwise not visible, e.g. in restricted mode, and thus be a
potential security hole.
"""

I wouldn't use it in any code I cared about, but it's a cool hack.

Peace,
  Kalle
