RepresentationTypeTuple! in std.traits does not work for classes.
It does work for structs.
Just not implemented yet?

import std.traits;
import std.stdio;

struct S {
  int a;
  string s;
}

class C {
  //public:
  int a = 2;
  string s = "xx";
}

void main (char[][] args)
{
  //works for struct
  alias RepresentationTypeTuple!(S) SR;
  pragma(msg, "S's field types: " ~ SR[0].stringof ~ ", " ~ SR[1].stringof);


  //same thing for class causes index out of bounds error
  alias RepresentationTypeTuple!(C) CR;
  // pragma(msg, "C's field types: " ~ CR[0].stringof ~ ", " ~ CR[1].stringof);
  pragma(msg, "C's field types? " ~ CR[0].stringof);


  C c = new C;
  writeln(c.a, " ", c.s);
}
