This is Lua 5.4.7, released on 13 Jun 2024.

But it actually isn't.

Lunar is Lua 5.4.7, transpiled to Rust using c2rust.

Lunar uses Rust's panic machinery instead of setjmp + longjmp, which unwinds the stack for RAII languages like Rust and C++.

There will be more features added in the future, like a tracing JIT.

Not in order.

• VM Interpreter Optimizations? Tailcall-based? Dynasm?
• Tracing JIT? (behind a feature flag)
• ???
• Syntax Extensions? Static Typing?
• Prolog-esque Backtracing? (behind a feature flag)
