> Ho nice! I guess we should move *all* from intervals to balls...
Eventually yes. But to be honest, I don't really understand why balls are
that much faster in this case, since the conversion from number field
elements to balls is optimized in the quadratic case only at this point,
and (I think) uses MPFI intervals internally otherwise.
> I would prefer doing it all at once.
Your choice! Yet it could be less effort to do it in new code before
trying to change existing code.
