Comment (by tscrim):
I was originally thinking that we should keep it as `isinstance`, but
since we explicitly construct a new `Rational` (and I don't think it could
be made to work with subtypes [easily]), I think we should only test
against `Rational`. Plus those extra little nanoseconds can matter at this
level. Subclasses can just fall into the coercion framework.
