You can get a list of classes in the executable at runtime from:

         foreach (m; ModuleInfo)
         {
           if (m)
             //writefln("module %s, %d", m.name, m.localClasses.length);
             foreach (c; m.localClasses)
             {
                 writefln("\tclass %s", c.name);
             }
         }
