Yeah, well done. All that duplicate code is painful to maintain, and
there have sometimes been bugs fixed in one of the two classes but
forgotten in the other. I agree we should start with option (c), but I
think we should view the rowind and colind attributes as internals
anyway, not as part of the interface. Ideally, we should keep adding
more high-level methods so that accessing rowind or colind outside the
sparse module is rarely necessary.
