[Haskell-cafe] How to declare a Typeless Function

Hi I have a function that swaps rows of an array of double swap :: Array (Int,Int) Double -> [Int] -> Array (Int,Int) Double I then create a function that swaps rows of arrays of Complex Double swap :: Array (Int, Int) (Complex Double) -> [Int] -> Array (Int, Int) (Complex Double) In reality the function swap does not care whether its working on a double or a complex number. how do I declare swap so that it will work whether it's a complex or a double array. I tried googling but I wasn't sure what to google. fernan -- http://www.fernski.com
