Quotes of the Week

   * romm: i thought i knew programming. this is like discovering a new
           continent.

   * edwardk: i think the comonads are warm fuzzy, and the monads are
     warm sticky. its easy to get out of a comonad, its soft and you
     like wearing it. monads on the other hand stick to you and are icky
