// redirect to a non-redirecting factory constructor or to a
// generative constructor in a finite number of steps.

// TODO(ahe): The above specification will probably change to
// something like: "It is a compile-time error if a redirecting
// factory constructor redirects to itself, either directly or
// indirectly via a sequence of redirections."
