Right, after the recent discussion, I now agree that filling with NaNs
is probably not a good thing. As far as I can tell, this only affects
operations that can generate NaNs (correct me if that is not right)
and not generating them is probably more useful behavior. OTOH, we
should fill with other values (for example, when doing something like
"speye (3) + 1").
