I know you can : go : : @foo = reverse (1 ..5); : : but this has the major disadvantage that it cannot be evaluated lazily; : reverse has to see the entire list before it can emit the first element of : the reversed list.
I don't see any reason why it can't be evaluated lazily. The .. produces a range object that gets shoved into the lazy list that gets bound to the slurp array of reverse(). If you pop that, there's no reason it couldn't go out and ask the end of the lazy list for its last element. Just have to make .. objects smart enough to deal off either end of the deck. Larry
