I'm interested in running Python inside wasmtime. I think PyO3 would be useful. We could build a small Rust wasm binary that exports an "execute_python_script" function. This would finally be a way to run Python in a strong sandbox with memory [0] and CPU [1] restrictions. (In 1999, I asked Guido for sandboxing support in Python, but he refused.)
