The accessors as I implemented them in the patch are getters
rather than setters or getter/setters.  I deliberatly avoided
making them do two things simply because I didn't need that
functionality.  What I did need, was the ability to get at
the property values from various parts of the code.  If the
accessors were changed to return $self then they would no
longer be accessors.
