I don't think those are actually traits. They look more like mixins.

If they were traits, there wouldn't be any point to also having interfaces, since traits are a strict superset of them.

Built based on this: http://php.net/trait

Depending on the language, I think they're pretty much the same thing; implementation of (read: copy) functionality from a stateless object.
