> Reason why you can't naively iterate over T.tupleof is that current tuple foreach tries to look like normal foreach and thus iteration parameters can't be  types. 

   void iterate(T)()
   {
       foreach (index, member; typeof(T.tupleof))
       {
           pragma(msg, __traits(identifier, T.tupleof[index]));
       }
   }
