Thanks for the reply, this is a static analysis pass so am I wrong in 
thinking that most of the functionality provided in cp is non necessary? 
For example, the front end already took care of whether or not if an 
access to a member variable was legal, what about other member variables?

Actually, that was the real question, nothing more. I need to be able to 
determine what member fields of an object passed to a function are visible 
to that function during an optimization pass. Is there existing 
functionality somewhere to do that?

Thanks again for the help,
