All the rules in the ASSOCIATE section are pointing to selectors being 
data objects, nothing seems to imply the possibility they being 
procedures.  If we were to allow procedures, then we need to include all 
possibilities of a procedure as a selector.  That includes procedure 
names, procedure pointer names, dummy procedures, procedure pointer 
components, etc.  I don't think we're ready to do that yet.  I'd be happy 
to limit the selectors to data objects for now, until we sort out all the 
mess of the implications of having procedure selectors.

Cheers,
