---

The gmp Mpq type does does it after each operation, and then exposes a raw interface for doing a few operations without normalizing. It only guarantees that operations are valid when the type is normalized. This leads to the most predictable performance with big integers, and avoids avoidable overflows for fixed size ones.

This would probably involve making the fields priv and using scary names for raw manipulation methods.
