> By the way, I'm not totally convinced myself that it's the best
solution. It is the best solution to the practical problem of backwards-
compatibility. But it does introduce some clutter: yet another list-like
type.
But it might be unavoidable: tuples must consist of immutable objects, so
it may not always be possible to return one.
