     auto ref opDispatch(string name, T...)(auto ref T args) {
         mixin("alias ." ~ name ~ " f;");
         alias ParameterTypeTuple!f Params;
         enum i = staticIndexOf!(Unqual!(typeof(this)), 
staticMap!(Unqual, Params));
         static assert(i >= 0);
         return f(args[0 .. i], this, args[i .. $]);
     }

(Doesn't work with overload set though.)
