+                  <pre>void sort(object_cref cmpfunc);</pre>

+
+                  This is because in Python 3 <code>list.sort</code> requires all its arguments be keyword arguments.
+                  So you should call it like this:
+                  <pre>x.sort(*tuple(), **dict(make_tuple(make_tuple("reverse", true))));</pre>

+                  when building Boost.Python against Python older than 2.6, the following macros will
+                  be defined in Boost.Python header:
+                <pre>
+# define Py_TYPE(o)    (((PyObject*)(o))->ob_type)
+# define Py_REFCNT(o)  (((PyObject*)(o))->ob_refcnt)
+# define Py_SIZE(o)    (((PyVarObject*)(o))->ob_size)</pre>
+                  So extension writers can use these macro directly, to make code clean and compatible with Python 3.
