Does anyone know if there is a function that tells you if a haskell
value has been forced or not?
e.g.
isWHNF :: a - IO Bool
let x = (map succ [0..]) in do
putStrLn . show (isWHNF x)-- False
putStrLn . show . head $ x
putStrLn . show (isWHNF x)

Note that this function [isWHNF :: a - Bool] is not
referentially transparent
Indeed. Does it still mess up with the result
