Nice development of combinators, and pretty readable. Not sure the
level of Haskell knowledge expected, but you might want to explain
pattern guards. Also, I believe your parser will fail if whitespace
appears at the front of the input - you might want to introduce a
"token" like combinator that drops whitespace as needed.
