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.
