Quotes of the Week

   * dafis: I thought a C++ friend class was one you allowed to touch
     your private parts

   * edwardk: any time i can help, just ask. i may not actually help, but
     i'll be sure to note your suffering.

   * edwardk: i have a lot fewer [haddock problems] now since i stopped
     bothering trying to document ;)

   * edwardk: Had i thought of it earlier i could have named trifecta
     kessel run. at this point it looks like it'll contain at least 12
     parsecs.

   * ddarius: The history of iteratees is making a simple idea complex.

   * shachaf: You can never escape having learned monads. If you learn
     two monads, though, you can go back to only knowing one.
