I meant it as "object attributes". We can't add new attributes to any of 
the nodes in the AST tree.

I think that the correct python term isn't "object" (everything is an 
object, even classes) but "class instance". I got that from:

    http://www.python.org/doc/current/ref/types.html

but maybe I'm wrong.

The "little slower" I was talking about would only be for jython and I 
don't think that the "little slower" speed would be much different from 
the speed of the pickling phase suggested by Jeremy.
