(snip john's version)

And what list would be complete without a points-free version.  It
doesn't operate on stdin, though like John's does:

pointsFreeCat :: IO ()
pointsFreeCat = getArgs >>= mapM readFile >>= putStrLn . concat

-- And a regular version for reference

cat2 :: IO ()
cat2 = do a <- getArgs
          lines <- mapM readFile a
          putStrLn $ concat lines
