This is documented, isn't it?
Many of these operations are only sensible for one-dimensional
arrays. Although they will accept input arrays of more dimensions,
the data is treated as though it were a linear array in storage
order.
I don't think anyone will thank us for changing intarray's behavior
many years after the fact.
