Ceylon: named arguments and declarative syntax for object creation

	class Director(String name) {

	Movie(
	"Avatar",
	Director("James Cameron"),
	{Actor("Sam Worthington"), Actor("Sigourney Weaver")}

	//now we are going to construct a movie using declarative object instantiation
	//As you can see this looks like a DSL language to construct objects whereas
	//in fact you're just making good use of named arguments
