When implementing a metatype in C (a subtype of PyType_Type),
aren't the tp_basicsize and tp_itemsize fields inherited?
This question is not covered in PEP 253...
I've attached the code below.
Thanks,
Thomas

#include <Python.h>
static PyMethodDef methods[] = {
{ NULL, NULL }, /* Sentinel */

PyTypeObject MyMeta_Type = {
