+Note that comparing objects of different types with ``<`` or ``>`` is legal
+provided that the objects have appropriate comparison methods. For example,
+mixed numeric types are compared according to their numeric value, so 0 equals
+0.0, etc. Otherwise, rather than providing an arbitrary ordering, the
