[David Ungar]

I’m not sure you get it: there is no signature, no such concept in Self. That’s part of what I’m trying to say. It’s a different model of computation.

The concepts are more like natural language concepts. If a thing wants to pretend it’s like a collection, it will implement do:. It may only partially pretend and not implement all of collectionness. But that may be fine for a particular use case.
