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.
