New submission from Raymond Hettinger:

In old-style classes, the memory address of the class object is shown for both 
the class and for the instance.  In new-style classes, only the instance shows 
the address.  I and other Python instructors have found the memory address 
display to be useful and I think it should be added back:

Old-style
=========
 
  >>> class A:
        pass

  >>> a = A()
  >>> A
  <class __main__.A at 0x10061e328>
  >>> a
  <__main__.A instance at 0x105292cb0> 


New-style
=========

  >>> class A(object):
        pass

  >>> a = A()
  >>> A
  <class '__main__.A'>
  >>> a
  <__main__.A object at 0x105332cd0>
