Hi Vincent, Hi Marc,
thank you for your comments.

thank you, fixed. I guess that this should also be changed in `RealBall`?

balls are different?!
thanks for pointing this out, `!=` is now the negation of `overlaps`.

good point, done.
Replying to [comment:16 vdelecroix]:

the same for interval field and ball field.
I'd also prefer to have the interval field with this behaviour (`a is b =>
a == b`) but how should that be done?
Won't it need a deprecation and possibly break lots of code?
The current status is that `RealIntervalField` and `RealBallField`
(intentionally) differ in their behaviour.
IMHO changing RIF is outside the scope of this ticket.
