What should we use instead? Array? nil when it’s empty? How about introducing some sort of a NilDictionary?

Would anyone like to experiment?

I think the use of SmallDictionaries for storing Famix state is not such a good idea. After loading the model:

bag := Bag new . SmallDictionary allInstances do: [ :each | bag add: each size ]. bag sortedCounts

"{530387->0. 19253->3. 18292->1. 20->2. 2->4. 2->11. 1->12}"

bag := Bag new . SmallDictionary allInstances do: [ :each | bag add: (each keys) ]. bag sortedCounts
