I can't speak for Alan, but my understanding was that this is not  
sufficient for the symmetry he was talking about.  The reason is that  
sending messages to the caller-object does not return the objects to  
the calling method.  What you need to get this sort of symmetry is  
(at the least) some sort of co-routine concept.
