 However, it seems like the code needs to call a C++ constructor (e.g. `new NativeFunction0<StaticFunctionTag, BSFixedString>("HelloWorld", "MyClass", HelloWorld, a_registry)`) in order to register a new native Papyrus function. Unfortunately, calling a C++ constructor requires FFI with C++, and [Rust does not support FFI with C++](https://stackoverflow.com/a/45540511).
