py> class A:pass
...
py> class B:pass
...
py> a=A()
py> id(a)
10781400
py> del a
py> b=B()
py> id(b)
10781400

Now if you look for id=10781400 you'll find b, which is another,  
absolutely unrelated, object.
Enabling this pointer -> objects ability would bring into Python the "wild  
pointer" nightmare of C programs...
