modifying a non-heaptype dict with PyDict_SetItemString before PyType_Ready should work
from Christian Tismer, he is doing something like this:
int add_more_getsets(PyTypeObject *type, PyGetSetDef *gsp, PyObject **doc_descr) ... PyObject *dict = type->tp_dict; ... if (PyDict_SetItemString(dict, gsp->name, descr) < 0) return -1;
PyType_Ready is called on the type. In PyPy this fails with the error

We could support this by allowing non-heaptype modifications before a call to
