[Haskell-cafe] A beginners question

Dear All, banging my head against Haskell, but liking the feeling of hurting brains. Just a simple question: If fmap (^4) [1,2,3] >>= \i -> shows i " " gives "1 16 81 " then why does let i = fmap (^4) [1,2,3] in shows i " " give "[1,16,81] " Probably very simple, but there must be a delicate difference between these two expressions. I just don't get it. -- Harri Kiiskinen
