In #19152, a `lazy_import` of `RBF` and `RealBallField` led to the error
{{{
File "src/sage/rings/real_arb.pyx", line 314, in
sage.rings.real_arb.RealBallField
Failed example:
(1/2*RBF(1)) + AA(sqrt(2)) - 1 + polygen(QQ, x)
Exception raised:
Traceback (most recent call last):
...
TypeError: unsupported operand parent(s) for '+': 'Real ball field
with 53 bits precision' and 'Univariate Polynomial Ring in x over Rational
Field'
