I was able to build something incredibly convoluted that accomplishes what you want, but I'm sure there's a better way to do it.

Not sure if it's a better way.

Disregard that reply, I overlooked the question. My only excuse is that it's early in the morning. that would be : unscan f l = if null l then [] else head l : zipWith f l (tail l) David. Where's my coffee ! Silly me. I don't drink coffee.
