The NaN package overwrites core functions, because Alois thinks
they're buggy. I disagree. The reason to overwrite them is that Alois
thinks NaNs should never be propagated in a calculation. The point of
the NaN package is to do this, to never propagate NaNs, but just omit
them from a calculation. So for example, in core Octave sum([1 NaN 2])
is NaN, but in Alois's package it's 3.
