Magic constants are evil. The above will not (automatically) remain correct
when new items are added to ary. Therefore:

              d = dict(enumerate(ary))

Make the above line

              if i in d:

instead. Faster and more robust against changes elsewhere (no need for
consecutive integer keys). 

You wouldn't want to teach a newbie bad habits, would you :-)
