This is super cool, thanks for looking into this! and sorry for replying
so late.  I agree that we should try and get these grammars integrated
into emacs as soon as we can, it's the end goal after all (by that I
mean that I'm not sure the Rust-based emacs module will live on after
emacs 29 is released).

But anyways, it's great that you got it working with minimal changes,
looks like there won't be any blockers :-).

Regarding the patch series, I do have a new version in the pipeline
(fixing style and improving testing) but I'm afraid I've had no time to
work on it in the past month and a half. I should have more time
starting from next weekend. 

Thanks!
Pierre
