[Haskell-cafe] Text.CSV questions

Hi, I try to parse csv file with Text.CSV, like this: import Text.CSV import System main = do [inpFileName] <- getArgs putStrLn ("Parsing "++inpFileName++"...") let result = parseCSVFromFile inpFileName print result === As a result I get: No instance for (Show (IO (Either Text.Parsec.Error.ParseError CSV))) arising from a use of `print' Possible fix: add an instance declaration for (Show (IO (Either Text.Parsec.Error.ParseError CSV))) === Question: How to add a Show instance for "(IO (Either Text.Parsec.Error.ParseError CSV)))" ? Thanks!
