| Actually your solution is recursive. Look that in your loop construct you

  you're right, of course.  the recursion that I find silly, and therefore
  reacted to, is using recursion to traverse lists, or recursing on the
  CDR.  for the sake of argument, I ignored the recursion on the CAR.  I
  think you made a good point for why that shouldn't be done.
