I see that the archetype provides the typedef, but what's the point of the static functions? You have to use the actual concrete type to call the right function, so having them declared in the base class doesn't let you use them in the manner of a virtual function.
It's not completely silly; given a static method A::F and a class B that derives from A, then attempting to call B::F will end up calling A::F if B does not define its own function that hides that. (And in this context, the base method presumably asserts or something.) Most compilers will generate a warning with this usage, though, so it's not really considered good style.
