Enable the use of the `attoparsec` package This library provides convenient combinators for working with and building parsing combinator libraries. Given a few simple instances, e.g. for the class 'Text.Parser.Combinators.Parsing' in "Text.Parser.Combinators.Parsing" you get access to a large number of canned definitions. Instances exist for the parsers provided by @parsec@, @attoparsec@ and base’s "Text.Read".
