let either = Either<Error, String>.right("Either")
either.fold( { _ in "Default" },
{ input in "Great \(input)!" } )
// Great Either!
```
```Swift
//: > __Bow__ provides us functional programming in Swift
import Bow
/*:
### Either
Sum type of types `A` and `B`. Represents a value of either
one of those types, but not both at the same time. Values
of type `A` are called *left*; values of type `B` are
called *right*.

let either = Either<Error, String>.right("Either")
either.fold( { _ in "Default" },
{ input in "Great \(input)!" } )
