[Haskell-cafe] Curry and uncurry

Hi The following is from the Hutton book: Without looking at the standard prelude, define the higher-order library function curry that converts a function on pairs into a curried function, and conversely, the function uncurry that converts a curried function with two arguments into a function on pairs. Hint: first write down the types of the two functions. I didn't even know about the curry and uncurry functions. I'm not looking for the answer but some guidance would be much appreciated. Thanks, Paul
