+Exceptions can be class objects or string objects.  Though most
+exceptions have been string objects in past versions of Python, in
+Python 1.5 and newer versions, all standard exceptions have been
+converted to class objects, and users are encouraged to do the same.
+The exceptions are defined in the module \module{exceptions}.  This
+module never needs to be imported explicitly: the exceptions are
+provided in the built-in namespace.
