+.. [5] To make enums behave similarly to Python classes like bool, and
+       behave in a more intuitive way.  It would be surprising if the type of
+       ``Color.red`` would not be ``Color``. (Discussion in
+       http://mail.python.org/pipermail/python-dev/2013-April/125687.html)
+.. [6] Subclassing enums and adding new members creates an unresolvable
+       situation; on one hand ``MoreColor.red`` and ``Color.red`` should
+       not be the same object, and on the other ``isinstance`` checks become
+       confusing if they are not.  The discussion also links to Stack Overflow
+       discussions that make additional arguments.
+       (http://mail.python.org/pipermail/python-dev/2013-April/125716.html)
+.. [7] It may be useful to have a class defining some behavior (methods, with
+       no actual enumeration members) mixed into an enum, and this would not
+       create the problem discussed in [6]_.  (Discussion in
