Hello, Noury,
Thanks for letting me see this but I wonder if it is good practice to place my own methods on the Object and UndefinedObject ?

Hi Roelof,
Polymorphism is the answer.
Object >> flattenInto: resultresult nextPut: anObject
UndefinedObject >> flattenInto: result^self
Collection >> flattenInto: resultself do: [ :item | item flattenInto: result ]
flatten: anObject^ (OrderedCollection streamContents: [ :stream | anObject flattenInto: stream ]) asArray
