[Haskell-beginners] Parsing an integer

[Tim Baumgartner]

Hi Stephen,

yes, it's Parsec, but I write this parser only for learning the
language, so I don't care if I rewrite existing code. But thanks for
the advice regarding performance. Patrick's answer was perfect for me
and I will get used to

<$> = fmap

soon.
