A meta comment:  I would highly appreciate if you stopped calling it
"Gaby's model". 

It is the *current C++ standard object model*.  If you don't like it; 
that is fine.  But, you don't have to like it.  (I don't).  But,
please don't call it "Gaby's model".  The fact that you don't like it
does not suddenly make it not the standard model.
