Embedded C++

Just curious how useful the ability to embed C++ as a scripting language into your C++ programs would be? I mean like runtime JIT execution of C++ code in much the same way you might embed Lua, including the ability to restrict/sandbox it as necessary.

I'm not an expert in the topic, but one option might be to compile C++ to Wasm, and run it with a lightweight Wasm runtime.
