[Haskell-beginners] help me with eroor

[Brent Yorgey]

By the way, if you need a CSV parser, there are several already on
Hackage: 'csv' [1] is the simplest; for more sophisticated uses there
are also bytestring-csv [2] and csv-enumerator [3].

But perhaps you are just writing a CSV parser in order to learn
Parsec; in which case, by all means carry on!
