// Hello, fellow Swift programmer!
//
// Here's a demonstration of a few ways of cleaning up the unwrapping of
// optionals in Swift.
//
// Swift is known to have both OO and functional background. Thus, there is
// probably some middle ground programming style that is *more* functional than
// Objective-C, and probably less so than Haskell. This playground tries to
// compare their differences in the pretty common scenario of dealing with
// errors or missing input.
