I often use an even more generic function:
splitter :: ([a] -> (b,[a])) -> [a] -> [b] splitter _ [] = [] splitter f xs = b : splitter f rest where (b,rest) = f xs
The name might not be ideal, but the general mechanics of it is pretty nice.
Have you looked at List.unfoldr? It's even more general. unfoldr :: (b -> Maybe (a, b)) -> b -> [a] Best regards, Tom -- .signature: Too many levels of symbolic links
