I was told that one has to sort them into SortedCollection, but the Set elements are not comparable (only identity compare, which i dont know how to use for sorting).

So is it safe to compare them like set1 = set2, or do i need to sort them (how for identity?).

I was thinking about some sortblock like this: [:pre :succ | pre OID < succ OID], would that work?

comparison set identity smalltalk
