[issue31791] Ensure that all PyTypeObject fields are set to non-NULL defaults

Serhiy Storchaka added the comment: 1. This will increase the size of type object. Most types are not numbers, not collections and don't support the buffer protocol, thus save memory for tp_as_number, tp_as_sequence, tp_as_mapping and tp_as_buffer. This also can increase the time of type crea

[issue31791] Ensure that all PyTypeObject fields are set to non-NULL defaults

pdox added the comment: I believe it would also make sense to inline the 'as' structures (tp_as_async, tp_as_number, tp_as_sequence, tp_as_mapping, and tp_as_buffer), instead of having them be pointers. This would save one pointer dereference with each use. But this would have API compatibili

[issue31791] Ensure that all PyTypeObject fields are set to non-NULL defaults

New submission from pdox : Ensure that every function pointer in every PyTypeObject is set to a non-NULL default, to spare the cost of checking for NULL with every use. As a basic example, consider PyNumber_Negative: PyObject * PyNumber_Negative(PyObject *o) { PyNumberMethods *m; if (
