We're in a stage of Swift's development where we can ask this question
fairly freely, and the fact that we expect to reach stability soon,
where it will be harder to ask the question, makes us ask it a bit more
often these days.  It's a balance; we don't want to create arbitrary
language churn, but we also don't want to be forever stuck with
decisions we'll regret later.
