    // NOTE: Do not allow construction of these objects from Python.
    //       Boost Python's shared_ptr_from_python will attach a custom
    //       deleter that releases the PyObject, which requires the GIL.
    //       Therefore it's unsafe for C++ code to release a shared_ptr
    //       without holding the GIL.  That's impractical so we just
    //       ensure that we don't create error objects in Python.
