Welcome to issue 236 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of July 8 to 14, 2012.

     not beautiful, I know that it is wrong.

   * Taneb: I'm doing the thing that every bored haskeller does one day
     and rewriting Prelude
