import std.stdio;

template Values(A...) { alias A Values; }

struct FlexMap {
   template opDispatch(string key) {
      auto opDispatch(VS...)(VS vs) {
         foreach (v; vs)
            writefln("%s: (%s)%s;", key, typeof(v).stringof, v);
      }
   }
}

void main() {
   auto fm = FlexMap();
   fm.list = Values!(1, "abc", 4L, 3.33);
}
