I don't think that change is necessary. We don't mandate the algorithm you use,
only that its result must be equivalent to the result of sum($arg) div
count($arg). We're now introducing an exception to that rule for the case where
that expression causes an overflow. We don't need any other exceptions, as far
as I can see.
