Comment:
I merged #18546 and #19063 as these tickets have been closed.
There is the following problem: #19063 uses the `experimental` decorator
on `ComplexBallField.__init__`. On the other hand, `CBF` is defined in
that module, which calls the constructor of `ComplexBallField`.
Here, in `matrix.py` I need to import `ComplexBallField` in order to check
whether the ring is a complex ball field. This immediately triggers the
`experimental` warning even if no `ComplexBallField` is constructed
explicitly, because `CBF` is constructed.
I see four options:
1. remove the `experimental` warning in `ComplexBallField` now.
2. remove the `experimental` warning in `ComplexBallField` once #19152 is
merged
3. move `CBF = ComplexBallField()` to a separate module, e.g.
`sage.rings.complex_ball_acb_default` and replace all lines `from
sage.rings.complex_ball_acb import CBF` by `from
sage.rings.complex_ball_acb_default import CBF` and undo this change once
the `experimental` warning disappears
4. fix doctests in 252 other modules whenever a matrix is constructed
which falls back to the generic implementation.
Suggestions?
