[Newbies] Traits

Thanks Matthew, that's interesting. I have never heard of traits.  So 
'uses:' is a way of incorporating behaviour/values which don't naturally 
inherit?

cheers

This is not a class; it is a trait. Traits are separate from
classes.

Object is not special; neither is it's superclass ProtoObject.
ProtoObject, the root object is just a subclass of nil.

uses: can be added to any class or trait definition to signify
that this class/trait incorporates some traits into it's
behavior definition. The only senders I know of in a stock image
are ClassDescription and TraitDescription; traits are not used
much yet
