I remember it being a complication with the mark hook that it could be
called on already swept objects in GUILE 2.0. So it mustn't go through
any virtual table mechanism as it must not rely on objects not already
being destructed. And of course there must be no allocations etc.
That's of course also doable with member functions but the headaches
might not be worth the gain.
