I kinda suspect that the NaN behavior was not designed but accidental.
What I'm wondering is whether it's really the "right", sensible,
behavior.

On reflection I suspect it isn't --- it'd bollix sum() or avg()
calculations over the function's results, for instance.  But now
I'm not sure zero is the right thing to put in, either.
