Well, AFAIK there's not really a good way to list all the attributes of 
a class in a general sense.  Even hasattr (I believe) just tries to get 
the attribute, and if it gets an AttributeError it returns false -- 
there's no backdoor introspection that gives you everything.  It can be 
a little frustrating sometimes.

I'd advise that you think about this in more explicit terms -- you 
aren't exposing all attributes, you really want to expose specific 
attributes.
