Please be more specific in what you mean by it not "seeing" the
dictionary, because the "reversed" approach *should* work:

$ python
Python 2.6.4 (r264:75706, Feb 25 2010, 01:21:39)
[GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> def foo():
.... bar = baz
.... print bar
....
>>> baz = {1:foo}
>>> foo()
{1: <function foo at 0x37b870>}

Cheers,
Chris
