`library/itertools.rst` declares `chain` as a function and `chain.from_iterable` as a class method immediately below, but refers to it as a function

Documentation

See more-itertools/more-itertools#1163. I believe separating the classmethod on chain outside chain, and using the func directive instead of the meth directive to refer to chain.from_iterable to work around this, to be suboptimal.

Hi, I would like to try fixing this documentation issue. Is anyone else currently working on this?

Not sure it is necessary to change. It is a class method FWIW. And documeint chain as a class feels wrong as well considering the rest of the page so I would leave it as js.
