Your own methods can be added to any class. Just ensure they are introduced as class extensions attached to your project's package. Use the checkbox at the bottom of the system browser.

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: result result nextPut: anObject
UndefinedObject >> flattenInto: result ^self
Collection >> flattenInto: result self do: [ :item | item flattenInto: result ]
flatten: anObject ^ (OrderedCollection streamContents: [ :stream | anObject flattenInto: stream ]) asArray
