It's a mirror of the question of importing ro. Doesn't zi'o na blanu have
the same set of valid no 0-tuples as does zi'o blanu? Consider zi'o jetnu
zi'o, which should be considered the negation of zi'o jitfa zi'o, and a
contradiction will emerge. If a statement and its negation are both false,
the statement should be considered meaningless. Falsehood should not be
considered the default truth value.
