If you just drop everything but your new method, it should work just fine.
class RF(Fraction):
def is_integer(self):
return self.numerator % self.denominator == 0
However, this doesn't ensure that operations on RFs will return more
RFs - they'll often return Fractions instead. There's no easy fix for
that, sorry.
