Templated Inheritance

[Jesse Phillips]

Templates, traits, mixins, and meta programming I haven't really gotten 
into. But I came to note that templating inheritance of a class works 
great.

My question is what others think about the possibility of using traits 
from D2.0 to allow for interface instantiation without reimplementing 
methods? I don't know how practical it would be but it might be quite 
interesting.
