Of course, this doesn't handle quoted values that contain commas, which
are among the many joys* of parsing CSV files.

I might just point out the existance of MissingH.Str.CSV to you, which
can read and write CSV files.  See
http://gopher.quux.org:70/devel/missingh/html/MissingH-Str-CSV.html for

A one-line call gives you a [[String]].

This uses Parsec, so it will not be a top-notch performer, but it is
elegant ;-)
