 For now, all we want to be able to do is to create new :class:`Noddy` objects.
 To enable object creation, we have to provide a :c:member:`~PyTypeObject.tp_new` implementation.
 In this case, we can just use the default implementation provided by the API
-function :c:func:`PyType_GenericNew`.  We'd like to just assign this to the
-:c:member:`~PyTypeObject.tp_new` slot, but we can't, for portability sake, On some platforms or
-compilers, we can't statically initialize a structure member with a function
-defined in another C module, so, instead, we'll assign the :c:member:`~PyTypeObject.tp_new` slot
-in the module initialization function just before calling
-:c:func:`PyType_Ready`::
-
-   noddy_NoddyType.tp_new = PyType_GenericNew;
-   if (PyType_Ready(&noddy_NoddyType) < 0)
-       return;
+function :c:func:`PyType_GenericNew`. ::

+   PyType_GenericNew,         /* tp_new */
 
 All the other type methods are *NULL*, so we'll go over them later --- that's
 for a later section!
