// Swift3 gets rid of dispatch_once and recommends replacing it with a lazy global.
// That's very straightforward when dispach_once is used to initialize something, but
// isn't an exact match when you want something to execute once, and then become a noop
// in a thread-safe way.

// The following approach seems completely "correct" and I guess actually a bit elegant,
// if by "elegant" you mean "terse and not immediately obvious to the reader, which makes
// you look very clever."

// 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.
