Hi, Simon!

Well, looking at the dumped instance with chicken-dump appears
to show something sensible, but the problem lies deeper: TinyCLOS
instances contain direct references to their class, which gets serialized
with the intance itself. But on deserialization, the class loses its identity,
and therefore the whole class-hierarchy of a deserialized instance
is invalid (we have several <class> or <top> classes in the end).
TinyCLOS has no notion of a global class table, which could be used
to map deserialized classes back to their "canonical" (i.e. system-wide)
identity.
So the bottom line is (currently) that instances (and thus classes) can not
be reliably deserialized.
