Mixins : Feature Request

[arpie42]

Would anybody else be excited to see mixins added to Monkey?

I should clarify what I mean by mixins as it is a term that can refer to various unrelated things. What I would like is something like D's Template Mixins or PHP's Traits

They are very very useful for reducing boilerplate and maximising code reuse. They are just all-round useful things and they make me happy whenever I use them.
