oh, right.  Hm.... what to do, what to do...

Ok, well here is a solution, but not the best one perhaps.  What you  
need to do is wrap lists in an object that adds an attribute called  
reverse. You can do this automatically by overriding ST.setAttribute.  
It will then auto wrap these objects as they come in.  You can then  
say $mylist.reverse$ in ST. :) Will this work for you?
