For further -- documentation, see http://haskell.org/cabal/users-guide/ name: exceptional version: 0.1.4.1 synopsis: Essentially the Maybe type with error messages. description: This is a very simple type: . > data Exceptional x > = Failure String > | Success x . It's much like @Maybe@, except instead of @Nothing@, we have @Failure String@. . A comparison could also be made to @Either String@. I made this library because I was dissatisfied with the @Monad@ instance for @Either@. In this type, @fail = Failure@. It's rather simple. . Changes . [0.1.4.1] Documentation enhancements/fixes. . [0.1.4.0] Added @fromMaybe@ and @toMaybe@ functions, and a link to the bug tracker. . [0.1.3.0] Fixed a typo. 0.1.2.0 won't build. Also added definition of @empty@ for @Alternative@. . [0.1.2.0] Added @fromEither@ and @toEither@ functions. . [0.1.1.3] Hackage is terrible. Yet another formatting fix. . [0.1.1.2] Yet another formatting fix. . [0.1.1.1] Formatting fix to the haddock documentation. . [0.1.1.0] Add @runExceptional@ function. . [0.1.0.1] Minor documentation changes. No changes to the API. .
