jython VS lucet

Quick note - CPython is the OG and most popular implementation of Python, but it is not the only implementation of Python. Some other fairly well-known examples are Jython (Java implementation), RustPython (Rust implementation), or the more mind-bending PyPy (Python implemented via Python 🤯). Python is an interpreted language, and you can think of all these different Python implementations as being different implementations of the interpreter itself. The interpreter is the program that takes your Python code and executes it via a virtual machine. This differs from a compiled language (like C) which needs the high-level C code to first be converted to machine code and then executed by the CPU.

The program I linked is the Python interpreter you're probably using, but the abstract set of rules that make up Python are not in any particular way tied to C. You could also use a Java program or a C# program to interpret your Python code. They've even made Python in Python itself, although it uses a more restricted version of Python so it's easier to compile it.

WebAssembly is extremely portable. WebAssembly runs on: all major web browsers, V8 runtimes like Node.js, and independent Wasm runtimes like Wasmtime, Lucet, and Wasmer.

The bytecode alliance had the lucet project which would be an OS executing WASM application, enabling very strict sandboxing.

References for anyone following: wasmtime Lucet

I guess lucet could be an under-layer for this but it's not really the same, different levels of the stack. Fascinating.

I also want to use this opportunity to say a big thank you to the teams working on Rust, Wasmer, Wasmtime, Lucet and waSCC. It would be impossible to build Lunatic without all the hard work put into this projects.
