amusing but very minor bug

[Okasaki, C. DR EECS]

I've recently been playing with functions with ridiculously
high arities.  When you get a type error, ghci conscientiously tries to
pinpoint where the error occurred.
Not only does it tell you the line number, it also tries to
give some structural clues such as

  ...
  In the 13rd argument of `foo', namely `bar'

or

  ...
  In the 12nd argument of `f', namely `g'

Of course, you see the problem with ordinals like 12nd and
13rd!  Obviously, fixing this should not be high on
anyone's priority list. :-)
