exceptional: A type for pure code that can fail.
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.
