Hm, from within module_for_little_classes that is globals(). To illustrate:

>>> import __main__ as main
>>> globals() is main.__dict__
True

Also, I'd spell module.__dict__ vars(module).

That said I agree that it's a good idea to use a dedicated module (not 
necessarily created on the fly) for those dynamically generated classes.
