--------------------------+----------------------------------
The fact that `arb` balls can have a precision different from their parent
is really confusing. It's different from anything else in Sage and leads
to strange things like
{{{
sage: a = RealBallField(20)(1.3)
sage: b = RealBallField(53)(1.3)
sage: a == b
True
sage: a+0 == b+0
False
}}}
