does anyone else think this would be useful to provide? Maybe
(sorry, couldn't resist :-) -iavor
module Data.Perhaps where
data Perhaps = No | Maybe | Yes deriving(Eq,Ord,Show,Read,Enum,Bounded)
instance Monoid Perhaps ... ...
I only ask because it has come up as useful several times in projects I work on.
