I would not bother with that, i.e. inventing some artificial
restrictions into the spec. Maybe there is a valuable use-case (I
cannot think of one, though), but the attitude to "forbid where one
cannot see a use now" has a touch of middle-european buerocracy :-)

So implementation may or may not catch that. Maybe at some point
processors will be that fast that that even terminates :-)
