HASKELL: I'm defining data types in Haskell. for example data Exp = Enum Int then I'm using the bar to define addition, multiplication, and logical not, logical else if. and also data Val = Vnum Int and also a boolean return value. I next want to write a function which takes an Exp as input and returns a value. What is the syntax for defining each data type? Right now I have: eval :: Exp -> Val eval (Enum x) = Vnum
