I would leave it unspecified, although I agree in restricting integer
arrays to exact integers. Is there any harm in a rule that a number that
would be inferred to be exact in an inexact array is treated as-if it
had `#i` prepended to it?

I don't like this sort of strict typing when a coercion would be simple
and obvious.
