Welcome to issue 282 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of September 22 to October 05, 2013.

Quotes of the Week

   * monochrom: . o O ( error messages are like legalese. it contains
     complete information so that later lawyers can say "told you so" )

   * BetaZiliani: "We escape from monads in the same way that we escape
     from a building on fire: we run." (#ICFP2013)

   * ReinH: ReinH's Lemma: There's always a connection to Yoneda's
     Lemma.

   * startling: it's sort of depressing when you spend a lot of time
     with traversals and things to get all your crucial algorithms down
     to like ten lines and then have like two hundred lines each for
     pretty-printing and for file I/O.

   * edwardk: you know that feeling when you wake up in the morning, and
     your teeth feel fuzzy, you don't know where you've been, but you
     strongly suspect in 9 months someone will be calling you for
     library support?

   * tac: I free the forgotten.

   * Anonymous: What do you call someone reading a book about category
     theory? A co-author!

   * Anonymous: A co-worker == generator of work tasks?

   * edwardkmett: At one point we had a type in lens where one of its 
     arguments started taking parameters of the form i m a s t a b u. 
     Upon reflection, we let it win the argument and decided 
     not to implement the function.
