[rucksack-devel] Practical ways of unlinking an instance from indexes

[Uwe von Loh]

I try to understand rucksack since several weeks now, but could not get 
the mechanism of deleting an instance. I tryed several approaches. The 
first was already mentioned in the list: remove the instance from all 
indexes by index-delete. That works for me in the case of class indexes 
but not for the slot indexes. Maybe I misunderstood the relationships 
between object-id and classes or slots.
My second (unsuccessful) approach was to slot-makunbound the slots of an 
instance. Can anybody help me with a short working example for that?
The third way to remove an instance was to change its class to an empty 
class (defclass nothingness ()()) as shown by Eric Naggum on cll. This 
way would be great, to remove an instance from all indexes at once but 
it didn't work for me either. Please give me some hints and examples on 
removing instances?
Thanks for your patience.
