Josh Stone 3f32ad48f4 rational: make sure Hash agrees with Eq ... We can't use a derived `Hash` when we have a manual `Eq`, because we need to uphold the invariant `a == b` → `h(a) == h(b)`. Since `Eq` doesn't require them to be in reduced form, `Hash` also needs to be normalized.		2017-06-29 11:52:25 -07:00
