Which is exactly the right sense.  Well, the only correct-ish option you
gave people is slightly awkward and inaccurate—I'd have said “Instances
of the conforming type can be expressed as integer literals,” but that
matches the 90% meaning almost exactly; certainly much better than the

As far as I can tell, your poll supports my suggestion.
