This doesn't need to be that sophisticated. Perhaps oddly, I do not need 
to know what members were *actually* accessed, just what *could have been* 
accessed. So in this case, I do not even need to know what is going on at 
the call site (which obviously simplifies things). Since you pointed me to 
the front end, do you know if there is a simple way of walking the 
inheritance type hierarchy to determine this? Right now I'm just walking 
it through the ..._CONTEXTs but it seems clumsy and I'm not sure if it is 
because it really is clumsy or because I'm still learning my way around 
the internals an I don't know what I'm doing.
