(when writing my Scheme hasher, I had a very hard time getting big integers to hash to the same value as equal reals; rationals would be a nightmare :() Perhaps they should be implemented as a Guile module (compiled or not). That way they would be an optional Guile feature. RNRS encourages Scheme implementations to support as much of the numerical tower as possible: (check!) complex (check!) real rational (check!) integer (small and "big") 3 out of 4 ain't bad.
