PEPs are often great documentation. They definitely don't cover everything, but they can be helpful

I find a bit infuriating that the official docs for pattern matching are the PEPs. Maybe that will change at the next pattern matching lang change, and I think PEPs and language docs each have their separate purposes, but on the other hand it's nice that the PEP is good (and current) enough as usage documentation.

how sad it is that the documents that described the changes exist as the reference for them, though.
