[ Note that this discussion, except maybe for the suggestion to add a simpler way to call a method with keyword args, is off-topic to python-dev. ]

I dont think I can use PyObjectGetAttrString because the subtype would return a reference to this function - rather then the lists original function, Id need an instance of a list and dont have one at that point.

Note that PyList_Type is a full-fledged PyObject, so PyObject_GetAttrString works on it just fine. Of course, you would also need to add the "self" argument before the keywords, but that's a trivial change to the function.

Calling PyObject_GetAttrString feels cleaner than accessing tp_dict directly, and most importantly call_method as written delegates creation of the dictionaty to Py_BuildValue.
