/I/ am the programmer when I write my code.  I know that it is very rare 
that I would want to access a read only object sometimes by value, 
sometimes via a pointer.  If it is a big object, the pointer will be 
useful.  If it is a small object, the value is most efficient.  So I 
don't need to go out of my way to be sure that an object can be 
efficiently access both ways.
