Speclists are typesafe. Speclists allow you to write

  struct genlist_iterator myiter;

  genlist_iterator_init(&myiter, &This->list, 0);

  for(; ITERATOR_PTR(myiter); ITERATOR_NEXT(myiter))
    if(((struct unit *)ITERATOR_PTR(myiter))->id==id)
      return ITERATOR_PTR(myiter);

as

  unit_list_iterate(*This, punit) {
    if (punit->id == id) {
      return punit;
    }
  } unit_list_iterate_end;
