I implemented something like this as an exercise: http://benmachine.co.uk/parconcat.hs It took me a little while to get everything to par as it should and I'm still not sure I'm doing it in the most efficient way, but there it is. (If the output is nonsense, you might try changing hPutStrLn stderr into putStrLn so that it's buffered and arrives in blocks). _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
