    // problem for SWIG though because it requires this in order for the object
    // to be properly wrapped to the C++ methods. So we need to wrap the
    // __setstate__() implementation around something that calls __init__()
    // first.  For symmetry, we also wrap __getstate__() as well. So in the
    // Python implementation, we define __getstate__()/__setstate__() that call
    // the internal _getstate()/_setstate() C++ methods.
