       I have a challenge for anyone who likes experimenting with Python and WebAssembly:Produce a short snippet of Python that takes a string of code in some other language (JavaScript, Lua or even Python itself), runs "eval" on it and returns the result, running that eval inside a WASM engine (using wasmer or wasmtime or wasm3) with restriction on the amount of CPU/memory available to that executionIt feels like this should be the "hello world" of WASM but I have not yet figured out how to do it!

       @simon I don't have the time write now to code up an example, but for wasmtime I think you're looking for its concept of _fuel_, which you can control from their Python API (and CLI): https://bytecodealliance.github.io/wasmtime-py/#wasmtime.Config.consume_fuel

       @brettcannon @simon here's something I duct-taped together: https://github.com/jimkring/python-sandbox-wasm

       Even without the sandboxing restrictions, I'd love to see example code  that loads up a WASM build of JavaScript/Lua/Python inside a Python host script and executes some code in it - I've not managed to do that yet eitherPart of the challenge is finding a documented .wasm file for one of those languages that I can download and then load inside Python - I really don't want to build one of those from scratch first

       @simon @brettcannon  you’re welcome. let me know if you have any questions or issues. I didn’t double-check the setup process and plan to add a GitHub workflow to test it all out on a clean machine.

       @jimkring @simon @brettcannon I took a stab at it: https://gist.github.com/pims/711549577759ad1341f1a90860f1f3a5Works on MacOS ARM.

       @simon I added CI (setup and testing) with github actions. It's passing! 👍 https://github.com/jimkring/python-sandbox-wasm/actions/
