Andrew, would you say you understand the original problem of why
mean xs = sum xs / fromIntegral (length xs)
was a bad idea now? Or why the left folds were a better solution?
i think that the problem is just what xs can't be consumed while it generated because it's used two times and this may be understood just by learning reduction graph as strategy of Haskell evaluation. isn't? -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
