Re: [Haskell-cafe] csv one-liner

Um... Does anybody else find it interesting that we are "showing the beauty of Haskell" by attempting to construct the most terse, cryptic, unmaintainable tangle of point-free code

I don't agree at all! How could a pipeline like this possibly be more clearly expressed than by the pattern: readInputFile "input" >>= mungeStuff >>= writeOutputFile "output" ? The OP asks for improvements, which got rid of a couple of gratuitous liftMs and such, but otherwise I think it's a pretty straightforward idiom. -k -- If I haven't seen further, it is by standing in the footprints of giants
