Interesting. So you're reflecting on a C/C++ API to dynamically export it
to Python space? Then I guess that your internal binding code is also
rather generic, right? It won't be able to call the application code
directly, for example, if it doesn't know the API at compile time.

Also interesting. I wonder who would notice with which tool you have
written your source code once it's compiled...
