> Regarding `center()`, I'd prefer to keep the name `mid()`, if only to
emphazise that the midpoint is part of the defining data of the ball (and
thus always is exact, while `mpfi_mid()` involves a rounding), but I have
nothing against adding `center()` as an alias.
For most practical purposes, the rounding or not is just an implementation
detail. Personally, I would prefer to use just one method name (for
example, I don't like that some types implement `prec()` and some
implement `precision()` but not all implement both: that's just
confusing). Given that `center()` has been around for a while, I would
prefer to use `center()` (and only that) also for arb.
