Welcome to issue 279 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of August 25 to September 7, 2013.

Quotes of the Week

   * dmwit: I typically figure a parse error on line 500 means I have
     500 lines to inspect.

   * bos: bah, all you category wonks spoil the atmosphere. we were
     simple peasants, and proud, once.

   * merijn: edwardk's delegation has reached the point where he can
     have the language implementor explain his libraries...

   * ReinH: haasn asks an offhand question. edwardk wrote a thesis on
     it.

   * JaffaCake: children are automatically killed if their parents die
     for any reason

   * geekosaur: if the platform is batteries included, lens is a full
     fledged transformer robot included :)

   * FreeFull: Mathematical laws are so much nicer than legal laws

   * twey: to edwardk, v. to be working on a larger problem and
     absent-mindedly spin out a package to satisfy dependencies,
     accidentally solving the problem more elegantly than existing
     solutions (but perhaps incomprehensibly to anyone who can't dualize
     in their head)

   * elliott: lens is the DLC expansion pack for Haskell

   * monochrom: new catchy thing to say: an IORef Int contains an Int in
     the same sense as an IO Int contains an Int
