Comment (by gagern):
I guess I should have thought two more minutes before pressing Submit.
Since you do call `_rational_` early in the loop, you can be sure that you
either detect critical integer or half-integer values, or there is some
finite difference between the value of self and the nearest critical
distance, so a finite number of added precision steps will be enough to
make the decision. Now things look pretty good to me.
