[Haskell-cafe] Enum to String, and back?

Hi, Using Show it is possible to establish a relationship between an enum type data Color     = Red     | Blue     | Green     | Yellow     | Orange     | Brown     | White     | Black     deriving (Show, Eq, Enum, Bounded) and a String type to display it. *Main> Red Red *Main> [Red,Green,Blue] [Red,Green,Blue] *Main> which is Red :: Color -> "Red" :: [Char] Can one as easily establish a reverse relationship, i.e., convert a String type like "Red" back to its corresponding Color type? So that "Red" :: [Char] -> Red :: Color Michael
