pywasm3 VS wasmtime-py

It's an embedding of the wasm3 library, and it exposes a function, `wasm-test`, that can call a function without arguments from a simple WebAssembly module. I intend to update it to reach feature parity with, for example, the python embedding.

PyOdide isn't currently supported outside of browsers, though that might change.

Either way, I couldn't figure out how to do the above sequence of steps with any of the available Python WASM runtimes - they're all very under-documented at the moment, sadly. I tried all three of these:

- https://github.com/wasmerio/wasmer-python

- https://github.com/bytecodealliance/wasmtime-py

- https://github.com/wasm3/pywasm3

You might look at https://github.com/wasm3/pywasm3 . If nothing else, it’d presumably speed up your interpreter to have bindings to an established C based runtime rather than re implementing the runtime in python

Wasmtime's `wasmtime-py` embedding in python has support for Wasm Components: https://github.com/bytecodealliance/wasmtime-py#components (disclosure, I helped create it)

The remaining piece of the puzzle would be to create a wit-bindgen guest generator https://github.com/bytecodealliance/wit-bindgen#guests for this build of the python interpreter. You could then seamlessly call back and forth between the host and guest pythons, without even knowing that wasmtime is under the hood.
