I don't understand this magic, but it seems to be working for me. I still 
have to specify all my classes by hand, though. 

If I do a dir() on an instance of my class, I get a list of ALL private
and public attributes. What is the best way for a program containing my 
SQLOject to get a list of the public attributes that object exposed in 
it's definition, excluding private and inherited items? The printable  
representation of the object looks like 

	<Customer 6 name='ACME' buyerID=1>

'_columns' lists the real columns, but not the proxied ones. I could also
just add a method in my class to return a list of fields. I'm thinking 
of generating a gui form based on what the object tells me it's fields are.
