Welcome to issue 222 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of April 1 to 7, 2012.

Quotes of the Week

   * tgeeky_: "What I cannot create, I do not understand." -- Richard
     Feynman, on his blackboard when he died in 1988.

   * elliott: ... [a] is more of a control structure than a data
     structure.

   * Cale: Basically, we've known how to implement first class functions
     efficiently for 20 or 30 years now, and we've known about their
     importance to abstraction in programming since before the advent of
     electronic computers. There's no excuse to still be writing new
     programs in languages without them.

   * edwardk: When someone throws an exception at you, duck.

   * luite: I think it uses levenshtein distance (he invented this
     distance because nobody could spell his name correctly)

   * edwardk: 'hey ghc devs can you fix this thing that might or might
     not be a bug so we can break a huge pile of invariants in your
     compiler to put go faster stripes on something nobody uses? k thx'
