traits are more than that. You can factor behavior and compose classes 
out of that.
We are working on a complete new clean/robust implementation that we 
will be able to load in 3.7.
This way we will have the same power as ruby with mixins.

Traits are backward compatible in the sense that you can always see the 
class in an old way (without traits). Of course
classes developed with traits will not load in VW. But this is the only 
way to progress and invent the future.
