This is the part that I miss, I guess. How can I wrap a class so that it works
like an exception in python? In the solutions on stackoverflow the translation
to an exception only happens in the translator, meaning that I cannot call
'raise MyException' in python, as it doesn't inherit from (the python)
Exception.
I've had a closer look. What if we take WindowsError as an example?
*) Define a new python exception CustomError with python/C APIs based on
WindowsError
*) Define a new C++ exception CustomException based on std::exception
*) Register a translator from C++ to python using CustomError as a target
Seems a reasonable approach.
