Here I need to let Python load the module first:

      PyObject* strMod = PyString_FromString("NrxDataTypes");
	PyObject* mod = PyImport_Import(nrx);

and for the PyImport_Import to succeed in debug mode, the .dlls must be
named foo_d.dll and libsip_d.dll, and the SIP generated NrxDataTypes.py
module needs to be in the module search path.

      PyObject* dict = PyDict_New();
      PyObject* tmp = PyString_FromString("tmp");
>     PyObject* val = sipMapCppToSelf(&value, sipClass_NDate);
	PyDict_SetItem(dict, tmp, val);
      PyObject* res = PyRun_String("2 + tmp.getYear()", eval_input,
dict, dict);
      long result = PyInt_AsLong(res);

It still doesn't work however. I get a 

  Fatal Python error: PyEval_SaveThread: NULL tstate

If anyone knows what could cause this, I would appreciate a pointer :-)
In the meantime I'll try to dig into it myself...
