    Concerning the point 8. There is an online Forth system demo Thurtle (in the browser) with turtle graphics, which is based on WAForth.

    Web49: WebAssembly Interpeter

    Project mention: Show HN: I wrote a WebAssembly Interpreter and Toolkit in C | news.ycombinator.com | 2023-01-09

    > I developed a unique way to write interpreters based on threaded code jumps and basic block versioning when I made MiniVM (https://github.com/FastVM/minivm). It was both larger and more dynamic than WebAssembly.

    I'd be very interested to read more about this. It looks like you are using "one big function" with computed goto (https://github.com/FastVM/Web49/blob/main/src/interp/interp....). My experience working on this problem led me to the same conclusion as Mike Pall, which is that compilers do not do well with this pattern (particularly when it comes to register allocation): http://lua-users.org/lists/lua-l/2011-02/msg00742.html

    I'm curious how you worked around the problem of poor register allocation in the compiler. I've come to the conclusion that tail calls are the best solution to this problem: https://blog.reverberate.org/2021/04/21/musttail-efficient-i...

    Research WebAssembly Engine

    Project mention: Wasmtime 1.0 | news.ycombinator.com | 2022-09-20

    Congrats to the Wasmtime team on the 1.0 release!

    I'm happy to see that more runtimes are maturing and getting use on production cases... I can't wait to see and show what the future entails for WebAssembly on both the server side and the browser!

    Keep up the good work. Also I'd like to use this message to congratulate other runtimes that I'm excited about (apart from Wasmer, of course!): Wizard Engine [1], Wazero [2] and Lunatic [3].

    The future is bright in Wasm land :)
