Again useful information failed to make it from my head to the
keyboard. :)  Currently I am looking at objects, regardless of their
types, and keying off their name.  If it is a module, class, or
function object, the name should be stored in __name__ already.  If it
is an instance of the Base class I demonstrated, I would like to
maintain that convention.

However, you may have a good point.  In other code I can simply check
for the name attribute I choose for my objects and also check for
__name__.  I suppose I just liked the idea of having a single
attribute to check.
