Yes, I also think it is an important point.  I'm not sure we should already
tackle the issue of having multiple representations of the *same* object,
though.  I was rather thinking about having several available implementations,
but each object only implemented with one of them at a time.  Occasionally
switching to another representation is the next step.  Managing several
concurrent representations is yet another, more difficult step I guess :-)


A bientôt,

Armin.
