If the reason there were 0 examples is because the group that you
posed the question to is lacking the kind of experience needed to be
able to provide them (speaking for myself, I wouldn't know because I
don't ever do anything with NaN beyond checking for it as an error
condition), then the point hasn't really been made, has it?
