Go 1.20 support is currently under active development, and nearing completion, with the exception of Generics support, which is simultaneously under active development.

Once these two objectives are complete, we'll be ready to work on Go 1.21, followed by 1.22.

If you have the knowledge and time to contribute to either of these efforts, that would be welcome.

Quick update here: I took a look at the code and your nice documentation about what is required to update to a new Go version, and quickly realized that it is quite a big task to get to a new version, and the updates for the loopvar syntax are a relatively minor aspect of that task. I did manage to implement a quick "hack" implementation of loopvar in the existing codebase and it seemed to work, so I'd be happy to contribute that once the rest of the heavy lifting happens to actually get to the 1.22 version.

If I somehow end up finishing all my other todo items before you get to 1.22, maybe I'll try to help out with wherever you are, but I suspect the collective expertise here makes you all much more efficient at that than I would be. And wow, javascript is kind of a nightmare! :)
