If I want to define a constant set in Python I would do this: class Colors: red = 1 blue=2 ...
and then I use them like this: Colors.red, Colors.blue...
Can I do something similar in Haskell?
In Haskell this would usually be an abstract type: data Color = Red | Blue | ... You could then use functions to convert between integers and colors. fromColor :: Color -> Int toColor :: Int -> Maybe Color You could also derive an Enum instance and get the conversion functions 'fromEnum' and 'toEnum' for free, although in that case the 'toEnum' function is less safe (no Maybe): data Color = Red | Blue | ... deriving Enum fromEnum :: Color -> Int toEnum :: Int -> Color Greets, Ertugrul -- nightmare = unsafePerformIO (getWrongWife >>= sex) http://ertes.de/
