2.2 Arguments

Another argument against NaI: there are different and contradictory
NaI concepts. For instance, if NaI is used for missing data, then
min(some_interval,NaI) should return some_interval, not NaI.


if NaI means illegal construction which is what this motion proposes
it must propagate



"There is an obvious analogy to 754 NaN"

Very partially. NaN can also mean [−∞,+∞] (any real number), as in
hypot(+∞,qNaN), or also the empty set (e.g. result of sqrt(-1)).


The fact that there are different uses for NaI suggest that NaI, if it
is made available, should exist with a payload, so that different uses can be distinguished.
