There are a couple of good reasons, centering around the value that references
have when passing arguments.  If we want to be able to write functions
(including operator functions) that accept objects rather than pointers as
written, but that actually pass pointers (for reference semantics or for
evviciency) we seem to be pretty well stuck to references.
