    // Retrieve the Python module called "some_module"
    python::object some_module((
        python::handle<>(python::borrowed(PyImport_AddModule("some_module")))));

    python::object some_class = some_module.attr("some_class");

    // assuming __init__ takes only a "self" argument
    python::object instance_of_some_class = some_class();

    // call instance_of_some_class.foo(3.14)
    instance_of_some_class.attr("foo")(3.14);
