@MasterQ32 - do you still maintain a grammar description anywhere in this codebase? I can’t seem to find it but would love to study it for this language.

I found this rep from your Zig talk with Loris…very nice implementation!

I guess i don't have a current grammer right now, but i can try recreating one if you want. Need to touch the project anyways the next days
