(This is the long-standing issue that C++ does not have expressions of
reference type.  Variables and data members can have reference type, and
functions can return reference types, but expressions as such always
have non-reference types.  But, we've never quite made the internal
representation consistent with that.)

I don't think it's possible for the internal representation to be any more consistent with that; we always have to deal with the actual pointer values, even if they are automatically dereferenced.
