GHC Haskell seems to be growing too rapidly syntax wise in my opinion. The important features of code are correctness, maintainability and readibility (IMHO), and I think => is working against these.
=> uses up more syntax. Buys very little. Equivalent to "-> Just _ " or "-> Just x " as far as I can see. I would prefer to type the extra 6 characters rather than having the hidden Maybe. It is also one more thing to learn. One more confusing type error when you mix them up.
