What makes you think there won't be a problem with the reverse. The caller
does not expect a reference but the calle returns one? In OOP the return
value of the derived class' method must be an instance of the class defined
by the base class' method or a subclasse of that. And so far we tream them
different, rather than a reference is a subclass of a normal value or vice
versa.

Best regards,
 Marcus
