For this use case it might be nice to have something simpler than a Generator. Instead of

Generator on: [ :generator |
    self allBehaviorsDo: [ :each |
        generator yield: each ] ])

we might want to write

    CollectionMaker on: [:workBlock | self allBehaviorsDo: workBlock] 

CollectionMaker>>do: aBlock
    ^doBlock value: aBlock

This would be much less tricky than Generator, because no coroutines are needed in this case.
