Point taken, I'm just trying to make like easier for myself (coding
g-p-m :-).

I agree now, "-1" makes most sense as a "unknown" value. DavidZ's idea
of not setting the key is also a nice idea as we are not providing a
value, although this gets tricky if the key is already set, as we will
then have to remove the key. I vote -1.

David, Danny?
