I think he has a C++ class that was exposed to Python, and which is
included as a member of a pure Python class. I think he would like to be
able to "implicitly convert" said pure Python class to the type of the
exposed C++ class, so that it can be used directly as an argument to
exposed C++ functions that expect the exposed C++ class as argument.

Maybe a possible solution would be to register a Python converter for your
wrapping class? This blog post was helpful to me when I had to learn how to
write custom to/from Python converters:

Hope that helps! Cheers,
