[docs] [issue29986] Documentation recommends raising TypeError from tp_richcompare

[Devin Jeanpierre]

Devin Jeanpierre added the comment:

Yeah, I agree there might be a use-case (can't find one offhand, but in principle), but I think it's rare enough that you're more likely to be led astray from reading this note -- almost always, NotImplemented does what you want.

In a way this is a special case of being able to raise an exception at all, which is mentioned earlier ("if another error occurred it must return NULL and set an exception condition.")
