Problem with modules refering to each other

I think this is one of those things I had to forget about from
the world of 'C'. In Python you don't need to have an object
defined by some .H file to use it. Besides circular reverences
importing this way isn't much different than having one large
module.

As you know one large module isn't a nice thing.

Try something like passing a parm that allows access to
an object in another module. The parameter approach also
allows you to change the relationships of these modules
at runtime.

Decoupling from other modules is a good thing.
