While this would be great if it could be done easily, I am more interested in exploiting order when I know in advance it is there. By the way, the Dictionary entry for I. is somewhat confusing in its use of the word "follows": I initially thought that 0 1 2 3 4 5 I. 3 was meant to be 4, not 3: I did not realize 3 followed itself.
