I would prefer

   repeat for each element x in y descending

but I doubt whether this would have the performance anywhere close to 
ascending 'for each' so it is probably pointless to have it. As far 
as I know, the speed of 'repeat for each' comes from processing 
elements sequentially and thus without having to recalculate the list 
pointer position.
