Would they even consider using D? Are you referring to a niche
for which D is not suited? In most situations you cannot afford
to develop a program to the point where it is 100% bug free, let
alone develop 2 independent versions of the spec to 100% bug
free. This is a very narrow niche.
And it isn't even relevant, because crash-and-burn-on-null is
still an option with voluntary recovery mechanisms.
And as I pointed out, you wouldn't use zero as a null value if
safety and debugging is your prime concern. You would use a more
"secure" bitpattern (i.e. harder to arrive at by accident), and
you would differentiate "null" from "undefined"?
