Another possibility would be a space delimited number list, easier for
your users to remember :

> parseWordList :: (Read a) => String -> [a]
> parseWordList str = map read . unwords $ str
>
> main = do
>   putStrLn "Enter a list of integers : "
>   line <- getLine
>   print . median . parseWordList $ line
