Regardless of whether we go any further it would indeed be good to be
explicit about the rules in the language reference and fix the
behavior of collections.Sequence.

I'm not sure about array.array -- it doesn't hold objects so I don't
think there's anything to enforce. It seems to behave the same way as
NumPy arrays when they don't contain objects.
