I agree that Pd objects should not be clones of max objects in this  
situation, and keeping things in the list domain probably makes the  
most sense.  But Pd is not entirely consistent in this.  One key  
example for me is that [route list] does not always output a list.   
(Yes, I know, sore subject perhaps).
