+""" For this example the control flow happens as follows::
+    import test_setup_flow_example
+    setup_module(test_setup_flow_example)
+       setup_class(TestStateFullThing)
+           instance = TestStateFullThing()
+           setup_method(instance, instance.test_42)
+              instance.test_42()
+           setup_method(instance, instance.test_23)
+              instance.test_23()
+       teardown_class(TestStateFullThing)
+    teardown_module(test_setup_flow_example)
+
+Note that ``setup_class(TestStateFullThing)`` is called and not
+``TestStateFullThing.setup_class()`` which would require you
+to insert ``setup_class = classmethod(setup_class)`` to make
+your setup function callable.
