Parsing - or why regexes are underused in Haskell

Friends of the Functional!

Something nice!
Something handy!
Something beginner-friendly!
An introduction to using `parsec`/`attoparsec`/`aeson`.

• `aeson` is the haskell JSON-parser du jour
• `attoparsec` is a parser combinator that has one thing in mind - speed (at the cost of error messages), can parse `Text` (a.k.a. better Strings) and `ByteString` (a.k.a. binary data)
• `parsec` gives great error messages - guess what it is slower

Some suggestions - please chose - simple attoparsec example (kata - from january)

• We can go through the examples from RealWorldHaskell (PPM, PGM pictures)
• Simple JSON parsing
• XML for the intermediate/advanced Haskellers out there with `conduit`
• your suggestion here

If anybody would like to present comment - I would be fond to have you!
