But I'm really not convinced by wideclasses,
because you will have to
define several classes and migrate on the fly instances between them.
Also, when "widening" is done one inst var by the other, there are
( n! ) possible subclasses for a class with ( n ) dynamic instance
variables. We would have to define working sets there, so maybe
__state__ is quite okay for the moment.
