// Swift Monads -- Maybe

// This operator can be used to chain Optional types like so:
// optionalVal >>= f1 >>= f2
// where f1 and f2 have type `Any -> Any?`
//
// If a value is ever nil, the chain short-circuits and will result in nil.
// This is a much neater way to do this than using the if syntax specified in
// the Swift iBook.
