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>
