That would cause problems with a lot of the software that I've written
(including PDF::Writer, I think), but Rational also has a #to_i method that
does what one expects. What won't work if you've got mathn loaded is:
a = 3 /5
b = a * 7
With 'mathn', that returns Rational(21, 5); without it, it returns 0.
I'm not sure what the right answer for this is, because I'm not sure that I
want to do "b = a.to_i * 7".
