The difference between math.nan and nil is that you can perform arithmetic
Actually, it would be sort of cool to have a NaN equivalent for other
operations. Call it NotAValue and perhaps it's actually the same as NaN. For
x = nil
y = x.field
y is now equal to NotAValue.
That would, however, change the semantics with respect to error detection.
