But I'd rather drop this property and allow the Spur GC to compact using best-fit and lazy become, which will change the order of objects. How important is being able to enumerate in order of creation? I think it's nice to have but hardly essential. What do y'all think?
The only use case I know of is being able to know when an object got created, enabling statistics on object age and fulfilling curiosity. Like, wouldn't it be fun to know the date that "nil" was created? ;)
E.g. in one of my images I have:

(attaching a breakdown with classes below). See class ObjectHistory in Squeak trunk for implementation details.
I would not see that as an essential feature, but just as a nice exploit of the old GC behavior. If it is simple to preserve it would be nice to have, but it should not stand in the way of better performance.
