+Add a new public :c:func:`PyObject_CallNoArgs` function to the C API: call a
+callable Python object without any arguments. It is the most efficient way to
+call a callback without any argument. On x86-64, for example,
+``PyObject_CallFunctionObjArgs(func, NULL)`` allocates 960 bytes on the stack
+per call, whereas ``PyObject_CallNoArgs(func)`` only allocates 624 bytes per
+call.
