Thanks for looking into it...

I'm a bit out of my depth with this stuff - from Googling the __main__
module in Ipython is actually a FakeModule - whether or not this is
designed to contain interactively designed stuff I'm not sure.

In [185]: __main__?
Type:           FakeModule
Base Class:     <class 'IPython.FakeModule.FakeModule'>
String Form:    <module '__main__' from
'/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/ipython-0.9.1-py2.5.egg/IPython/FakeModule.pyc'>
Namespace:      Interactive
File:
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/ipython-0.9.1-py2.5.egg/IPython/FakeModule.py
Docstring:
    Simple class with attribute access to fake a module.

    This is not meant to replace a module, but to allow inserting a fake
    module in sys.modules so that systems which rely on run-time module
    importing (like shelve and pickle) work correctly in interactive IPython
    sessions.

    Do NOT use this code for anything other than this IPython private hack.
