Line 480:
let s = "Some string."
mapM_ (\f -> putStrLn . f $ s) [remFirst, remLast, remBoth]</lang>
Alternative solution with builtin functions:
<lang Haskell>word = "knights"
main = do
-- You can drop the first item
-- using `tail`
putStrLn (tail word)
-- The `init` function will drop
-- the last item
putStrLn (init word)
-- We can combine these two to drop
-- the last and the first characters
putStrLn (middle word)
-- You can combine functions using `.`,
-- which is pronounced "compose" or "of"
middle = init . tail</lang>
