Python has good multiple inheritance and as far as I've seen most sane people just use it to "emulate" mixins and even name their secondary parent classes like Feature1Mixin or DoesYTrait.
Traits seem like a great idea, but the only other language where I've seen it under the Smalltalk name of "trait" is... brace yourself :) ...PHP 5.4+.

Scala has traits, to great effect.
