PEP 634 has not yet been accepted, but we'd like to hit the ground running and get this into alphas as soon as it (hopefully) is.

Several people have volunteered to review the implementation, since it's so huge. Other reviews are very welcome, if anybody has a bit of time to pitch in. This touches tons of stuff: the parser, the compiler, the VM, the builtins, the stdlib, the tests... I'd like as many eyeballs as possible!

I'll have a draft PR up against master in a few minutes. Let's try to keep all of the review comments there.

Sorry, just resolving some changes with master. Are you parser people finished breaking my grammar yet? Sheesh. ;)

Thinking ahead...

A lot of work has gone into writing these PEPs...  we should see how much we can easily convert into actual docs. It seems to me:

- Parts of PEP 634 and PEP 635 can be worked into the language reference.

- Guido's overview (the appendix of PEP 636) can probably just be dropped verbatim into the What's New for 3.10.

- The rest of PEP 636 can just be lifted into the docs as a proper tutorial and linked to from the What's New.

Also, we need to document the stdlib changes (ast, collections, dataclasses, keyword, ...). The dis module docs are already part of the implementation.

If you feel up to it, you might see if you could open a new, separate
(draft) PR that updates all those docs. (But you could also wait and see if
someone volunteers. There are some good doc writers active ATM.)

I'll wait till the SC makes a ruling, then send a message to our docs list (I think we have one)? I'm fine coordinating/reviewing that, or making PRs myself if nobody else steps up.
