This is cool because it avoids emulation. However I think it has many shortcomings today which could all be solved by emulating a real CPU architecture (e.g memory protection support, ecosystem with tooling and Linux distributions). By the

You can try https://edubart.github.io/webcm/ WebCM is a serverless terminal that runs a virtual Linux directly in the browser by emulating a RISC-V machine. It's powered by the Cartesi Machine emulator, which enab

Main differences in emulation context: - The Cartesi Machine can run any Linux distribution with RISC-V support, it emulates RISC-V ISA, while CheerpX emulates x86. For instance the Cartesi Machine can run Alpine, Ubuntu, Debian, etc. - The

You are correct, when not using the GC and doing manual memory management the code will be unsafe as similar as in C, but the language generate some runtime checks (that can be disabled) to minimize undefined behavior. Nelua does not provid

Terra was an inspiration to create Nelua in its metaprogramming aspects. Terra's famous Brainfuck example (on the front page of Terra) is available in Nelua's examples folder for comparison of meta programming.

Teal add type annotations and type checking to Lua, and transpiles to Lua, while Nelua is a new systems programming language with optional type annotations and compiles to C. @ubertaco also made a good comparison in his comment with Teal.

Actually Nelua have been tested to work with Arduino, AVR, RISC-V and some other embedded devices. You can make some free standing code with the language if you follow some rules (avoid APIs that uses lib C and use a custom allocator).

You are correct, but this is an enhancement to have better compile time type checking and runtime efficiency. In the future _G table with similar Lua semantics is considered to be implemented to have better compatibility with Lua code. But

You could change the language grammar through the preprocessor to accept "let" as an alias for "local". But I recommend people get used to Lua syntax because the metaprogramming will be done in Lua anyway, thus both prog
