The real issue I see here is that the xrefs aren’t appropriately prefixed with ~ for some reason, meaning object is repeated over and over doubling the length of each link and looking much more repetitive and distracting. The fact that the actual dunders are documented on object is mostly an implementation detail and distracts rather than add clarity here, and in most other places as well. Furthermore, the fact that they are linked makes it generally less vital to fully qualify names in the text referring to them, since that information is encoded in the link. In fact, it might even be viable to go so far as to always add ~ to object.__dunder__ links via @nedbat 's Sphinx extension, at least when the link is not suppressed.
That’s great, Ned! I think we may have discussed some kind of Sphinx extension like that which would auto-suppress self-links and multiple links within the same context, like that when we first hashed out the style guide on this, and I may have even played around with prototyping something like that but (like many things) I never got around to actually implementing it for real. Good on yah for making it happen!
