That's from a course that was given in 2004. UNSW has been teaching haskell for much longer, in those days everybody doing CS had to learn haskell.<p>Still a dearth of useful programs written in haskell in 2016. I've never seen a Haskell lover attempt an explanation that wasn't pure booster-ism. Why are there so few useful Haskell programs? Haskell has had time and access to programming talent and come up with very little. Maybe it's just around the corner hanging out with the year of the linux desktop?
