Don't forget about templates (appear as members too, but don't have a type).


This will print all fields of struct/class S:

   enum s = cast(S*)null;
   foreach (i, m; s.tupleof) {
      enum name = S.tupleof[i].stringof[4..$];
      alias typeof(m) type;
      writef("(%s) %s\n", type.stringof, name);
   }

Real Programmers don't use std.traits. ;)
