This functionality pretty hard to work with.

I've tried to use it for one C++ library and finished with the 
approach of manually prepared C API for C++ API and ImportC. It 
worked much better approach.

Examples are here
https://github.com/cyrusmsk/gguf-converter/tree/main/libs_tests

Simple C++ interop was working with D (separate folder where I've 
tried to compare this with popular ML/AI langs).

But when I tried to use it with real C++ library (sentencepiece) 
that I wanted to use (sp folder) - it failed with C++.

It was non-straightforward how to define namespaces and how to 
work with string_views.


If anyone could fix this C++ library - would be interesting to 
see.
