Guarding when import module in python

[MarcJos]

Dear all,
How is it possible to use "guards" when importing a Python module generated by pybind, i.e. PYBIND11_MODULE ?
More specifically, I would like that, when writing
import my_pybind_module
in python3, an (invisible) C++ object my_object is created, and that this object is deleted when stopping the python interpreter. This object contains the environment that is necessary for the module. Said in other words, I would like to code something in the pybind interface like
#include <pybind11/pybind11.h>
PYBIND11_MODULE(my_pybind_module, my_pybind_module, py::call_guard<my_object>()){
...
}
which is not possible.
Actually, I could create functions my_pybind_module.initialize() and my_pybind_module.delete(), but it would be tedious for the user to remember to write them at the beginning and at the end of their python script.
Thanks a lot for your help!
With kind regards,

Marc
