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.
