Read an integer list in Haskell

Was browsing my feed and came across something similar to this in stack overflow. So really quickly wrote out the imperative version:

readInts :: String -> [Int]
readInts x = read x

main = do
  input <- getLine
  let list = read input :: [Int]
  print list

Then I of course rewrote it to the condensed version:

readInts :: String -> [Int]
readInts x = read x

main = do
  getLine >>= print . readInts

I attempted to get rid of the readInts function like this:

main = getLine >>=  print . (read :: [Int])

However I was met with the type error and… I apparently never finished this post. Maybe later?
