Embedding RustPython in a Java environment

[Yu-Vitaqua-fer-Chronos]

Heya, I already made it an issue but it'd likely be much better as a discussion so, here: #3985

Title: "Exposing functions/classes from Java (using a WASM runtime) to RustPython"

Description: Heya, the title says it all haha, I'm interested in trying to embed RustPython into my Java application, and I want to use it as a scripting language, but I don't know how I'd expose a function to it at all really, is there anything specific I'd need to do? Any advice to use this within Java too? GraalVM would be ideal but as that isn't an option for me, I'd like to look at other ways of doing this

There's also been a few replies here
