 third-party callables should include a ``vectorcallfunc`` function pointer,
 set ``tp_vectorcall_offset`` to the correct value and add the ``Py_TPFLAGS_HAVE_VECTORCALL`` flag.
 Any class that does this must implement the ``tp_call`` function and make sure its behaviour is consistent with the ``vectorcallfunc`` function.
-Setting ``tp_call`` to ``PyCall_MakeVectorCall`` is sufficient.
