+\item A new type object, \class{basestring}, has been added.  
+   Both 8-bit strings and Unicode strings inherit from this type, so

+   either kind of string.  It's a completely abstract type, so you
+   can't create \class{basestring} instances.

+\item Most type objects are now callable, so you can use them
+to create new objects such as functions, classes, and modules.  (This

+Python version, because you can now use the type objects available
