I dedicate this to Dan S., who taught us to avoid parentheses like never before.

Thanks!

I have little idea of what's really happening in the background, but I am leaning towards trusting you and @tthsqe12 on their good work. With the missing bracket added, maybe we do not even need to fix the doctests.

Edit: It seems that I don't have the right to push to this pr. I will leave a suggestion, then.

Very nice. Can/should this be backported? (I don't know if it affects the book)

[HechtiDerLachs]

Yes, I think it should be backported. At least #3437 must be backported, since the output is just wrong. Then this one doesn't seem to hurt on top of it.
