Welcome to issue 232 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the

Quotes of the Week

   * irene-knapp: ewtoombs: the universe is already an interactive
                  quantum physics simulator

   * Philipp: "While in Python every problem can be solved with a big
              enough Hashtable, in Haskell, every problem can be solved
              with an additional type parameter."

   * kulin: man, i am loving this existential quantification, i feel
            like now i will use it incorrectly to solve every problem for sure

   * mekeor: xmonad is awesome (ignore the ambiguity, please)
