I remember seeing this a long time ago and liking it, I just didn't have a use for it at the time. How does it stack up against luahit for perf and memory, and threading? It also looks like it could be worth looking at porting the compiler to zig which excels at both compiler writing and cross platform tooling.

LuaJIT is best in class performance for a scripting language -by a huge margin. In very specific problems, it can outperform C. Surely anything else is going to come up lacking if you are only considering raw benchmarks.
