It would be interesting to note that CLOS (Common LISP Object System)
specification -requires- the conforming CLOS implementation to cause
all the instances of a class to change whenever the class definition
is changed at runtime - even if their internal representation is
expanded.

Obviously, this isn't trivial to implement without nasty performance
penalties, but it definitely is doable.
