[Pharo-project] SmallDictionary>>removeAll or >>empty?

Stupid question: how do I remove all entities from a SmallDictionary Let's take: d := SmallDictionary new. d add: $d -> 4. d add: $e -> 5. d If I do d empty then d size = 0 and d do: behaves as if there is nothing BUT someone can still perform d at: $d -> 5 If I do d removeAll I get a MessageNotUnderstood: SmallInteger>>key because #removeAll inherited from Collection expects a different structure -- Simon
