The DescrConverter function is meant for "O&"-style conversions. It
can't accept an align function. We could possibly add something to the
converter to allow specification of alignment through the object to be
converted.
Or, you can just call the __new__ method of the PyArrayDescr_Type object
res = PyObject_CallMethod((PyObject *)&PyArrayDescr_Type, "__new__",
"Oi", dict_object, 1))
or call the tp->new method directly:
args = Py_BuildValue("Oi", dict_object, 1);
PyArrayDescr_Type->tp_new(&PyArrayDescr_Type, args, NULL);
Py_DECREF(args);
(I think passing in NULL for the keywords is O.K., but I haven't checked
it).
