As an example of this sort of thing, I know that there are only 4 values of type a -> Bool (without the class context). They are the constant functions (\x -> True), (\x -> False), and two kinds of failure (\x -> _|_), and _|_, where _|_ is pronounced "bottom" and represents something along the lines of nontermination (aborting the program also counts).
Don't forget (\x -> x `seq` True) and (\x -> x `seq` False). -- Ben
