+Classes
+-------
+
+Python 2 has two core class hierarchies, often called *classic
+classes* and *new-style classes*.  The latter allow for such things as
+inheriting from the built-in basic types.  However, confusion and
+inconsistencies between the two class types has led Python 3 to drop
+classic classes.  Now all classes in Python 3 are *new-style*
+(although that's a misnomer now).  There is no need to inherit from
