This is certainly worth discussing, but there's always a heavy
burden of back-compatibility; how much better would it be for NCOL and
NROW to both return zero, vs. the amount of old code that would be broken?
Furthermore, the reason for this behaviour is justified as
consistency with the

The point is whether it might be worth it to make NCOL and NROW return
the same value on NULL and make R more consistent/intuitive and

I do not know what would be the 'correct' answer to the following but
I think that they should return the same value to avoid potential
