Quotes of the Week

   * dmwit: Let's not make things better, I haven't put enough lipstick
     on the worse version yet.

   * mike-burns: Oh good, a semantic argument. Goodnight.

   * companion_cube: why bother with complicated abstractions like
     monads, when you can enjoy the taste of the sun on your skin?

   * applicative: clearly the trouble with haskell is plain: no inbuild
     syntactic support for quaternions. Wonder if *fortress* has it.

   * elliott: "with a lot of unicode" is like agda's @faq. "yes, agda
     can do that with a lot of unicode!"

   * [shachaf] mauke: EBCDIC?
     [mauke] shachaf: ah, the data encryption
             	      standard invented by IBM?

   * Tiwazz: It's called "Berp" because that's the sound Haskell makes
     after it devours a live Python.
