Hi, very interesting bug.

Do we do something similar with some docstrings in bokeh / other tool wraps?

[JohannesBuchner]

Is that question for me? I don't use bokeh, and this is not the bokeh repository, and I am confused who you are addressing with "we"?

[JohannesBuchner]

FWIW, I installed bokeh and python3 -OO -c 'import bokeh' works fine.

Haha, sorry for the confusion -> we = arviz repo

Also just noticed that these are actually touching the docstring hacking parts I remembered. It has been quite a while since I look into this part of code.
