My only objection is that this introduces two new keywords, trait and instead. In addition, this can get very awkward if multiple traits (more than 2) implement the same method name. I would prefer a simple recycling of the "=" sign for both use cases (I'd also accept = for override, "as" for alias). class Talker { use A, B, C, D { smallTalk = A::smallTalk; // this says that if B, C or D implement smallTalk, it is ignored talk = A::bigTalk; } } To everyone - this is an aliasing procedure, not a renaming one, and won't affect internal methods of a trait (such as if B::whatever used B::smallTalk), as Richard Quadling incorrectly suggested.
