9485 :: High-to-low range in slice

  OK, I know the question is nothing so important per se, but I'm asking for the sake of it.

  Let's say I have an array/seq and some slice:

  arr[x .. y]
  Run

  Apparently, this works only if x <= y.

  What if x > y? Is there any way to do it, using something along the same lines?

  If you want to reverse a seq, use reverse, don't play ASCII art games.

  I assume the reasoning is to prevent something akin to integer underflow, as right now, it simply won't work. so being more explicit to prevent unintentional bugs... but maybe I'm wrong.. the reasoning could be aversion of ascii art games :-)
