I believe that template mixins + structs are much more natural
way to express this concept. Basically, if you need inheritance
only for code reuse, you don't need inheritance and all
polymorphic overhead. D provides some good tools to shift away
from that traditional approach. Those can and should be improved,
but I think the whole concept "classes are polymorphic virtual
reference types, structs are plain aggregates" is very solid and
area of struct-only development needs to be explored a bit more.
