Welcome to issue 257 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of January 27 to February 02, 2013.

Quotes of the Week

   * shachaf: Everyone forgets about Agda Lovelace, the first
     constructivist.

   * applicative: I have my new ghc and am reinstalling my feeble world

   * wuttf: My world is starting to feel like isToyLanguage x = x /=
     Haskell

   * PenguinOfDoom: Being enlightened gentlemen, we split all
     programming languages into two groups, sucks and doesn't-suck and
     put all of them into the first group.

   * Taneb: lens has got to be the only library with more contributors
     than people who know how it works

   * shachaf: I like to put all my application's modules under GHC.*
     That's because I use the GHC API, and I want them not to conflict.
