They could be made simpler (avoiding a few specializations) if you
didn't try to do an nonintrusive example.  E.g., this stuff:

       template <class Iterator> struct apply; // never defined

       template <class Struct, int index>
       struct apply<foobar<Struct,index> >
       {
          ...
       };
