I've noticed about the empty_base class is that it's templated with type T, 
and I don't think it should be.

Fyi, the empty_base class is there to turn multiple inheritance into a single 
inheritance chain (due to compiler deficiencies/object size bloat on at least 
Visual Studio).

I don't see why this empty_base should be templated, and it would be better 
suited if it wasn't since all I can think it does is make the compiler work 
harder. Does anyone know why it was templated to begin with? Additionally, are 
we safe to change empty_base to be not use templates?
