Your point is well-taken and I rewrote the function as:

static define get_bound_key (search_func, default)
{
   foreach ([which_key (search_func), pop()])
     {
	variable key = ();
	if (strlen (key) == 2)
	  {
	     if (key [0] == '^')
	       return (key [1] - '@');
	  }
     }
   return default;
}

Thanks,
