[Haskell-beginners] Converting a data type to an abstract data type

I had defined a data type similar to the following: data Record = Record { name :: String, age :: Int } Later, I realized I needed it be an ADT defined like: data Record a = Record { name :: String, age :: Int, resource :: a } The change turned out to be fairly well contained and probably only took me a half hour to propagate up. However, I see the potential for this to be a bigger job. Are there any editors that automate that kind of refactoring? -Ryan
