Oh awesome, thanks! I know I'd love to see automation for an in-tree grammar up and running personally. I'm not sure what the efforts are in terms of an official grammar and where it's supposed to live. Maybe ping the In the meantime seems like a good improvement regardless :) @bors: r+ rollup |

Update grammar to parse current rust syntax Mainly addressing rust-lang#32723. This PR updates the bison grammar so that it can parse the current rust syntax, except for feature-gated syntax additions. It has been tested with all the tests in run-pass. The grammar in this repo doesn't have build logic anymore, but you can test it out in https://github.com/bleibig/rust-grammar, which has all of what's in this PR. If you are interested in having build logic and grammar tests again, I can look into implementing that as well. I'm aware that things are somewhat undecided as to what an official rust grammar should be from the discussion in rust-lang#30942. With this PR we can go back to having an up-to-date flex/bison based grammar, but the rustypop grammar looks interesting as well.
