polynomials guys ...
Ok, sorry, I'll try to avoid doing that in tickets you are likely to
review.

that I'd prefer to state that

actually returns a new ball).
Done.
> I'd prefer something which separates the two messages of the one
sentence, e.g. "Use `__nonzero__()` to check that a ball is not exactly
the zero ball (for instance, to determine the “degree” of a polynomial
with ball coefficients). In fact, `__nonzero__()` is the negation of
`is_zero()`, whereas `is_nonzero()` only returns `True` if `0` is known
not to be in the ball."
Done.
> Further remark:
>
> 19. The AUTHORS section at the beginning of the files is not accurate: I
started those files, but most of their contents has been written by you.
So please either add your name or remove mine.
I'll be consistent with what I said on sage-devel a few weeks ago and
simply remove the AUTHORS block :-). But of course please feel free to add
us both back if you prefer.

> I would not mind having RBF, CBF, RealBallField and ComplexBallField in
the global name space; this is how most of sage seems to work. But this
could also happen in another ticket ...
Done — I still don't like that very much, but since everyone seems to
agree...
