RE: [Haskell-cafe] How Albus Dumbledore would sell Haskell

G'day all. Quoting Simon Peyton-Jones :

Lots of interesting ideas on this thread, and Haskell-Cafe threads are *supposed* to wander a bit. But, just to remind you all: I'm particularly interested in

concrete examples (pref running code) of programs that are * small * useful * demonstrate Haskell's power * preferably something that might be a bit tricky in another language

I updated the diff example a bit: http://andrew.bromage.org/darcs/diff/ It now features TWO newtype synonyms. This illustrates a crucial feature of Haskell: Abstractions are cheap. Cheers, Andrew Bromage
