Well, yeah, exactly.  The point is that it is being made harder to
teach by that obscurity introduced by the overloading of SET! (or = or
whatever it's called in their favorite programming language).

But it makes explicit a conceptual difference people need to
understand anyway which is a good thing.  Overloading could collapse a
lot of procedures and special forms into one in just about any
language, but that doesn't make the idea inherently elegant.
