-- Given an expression N, determines if the expression is a reference

- -- reason that this is in Exp_Ch2 is that it has to deal with the
- -- case where the reference is to an entry formal, and has been
- -- expanded already. Since Exp_Ch2 is in charge of the expansion, it
- -- is best suited to knowing how to detect this case.
