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"
interact pureMungeStuff After all, you're looking for oneliners, not real programs. interact $ either (error . show) (printCSV . map updateLine) . parseCSV "<stdin>" Claus -- some people need a vacation
