uj supplied this:

About the discussion "putStrLn (readLn + (5 :: Int))"..

I'll write it as the following line,

importing Control.Applicative main = (+) readLn (return 3)

They look almost exactly same in my eyes..

You're missing some bits.

main = print =<< liftM2 (+) readLn (return 3)

Which I assert looks like more line noise than some perl programs I've read. :)

Or using idiom brackets (for example from SHE): main = print =<< (| readLn + ~3 |) or main = (| print (| readLn + ~3 |) @|) Regards
