err this is backwards. We should write the mutative method here, and then have Power just make a copy then run PowerMut

Or just delete power mut for now
Unless the idea is to keep this as an API stub, to optimize later?

I'm happy to delete this for now.
Since we rely on Exp2 function for the underlying implementation, making a mutative PowerMut is not as trivial as making MulMut.
