Summary: 2.2a1: New style classes and __delitem__

Initial Comment:
And another one: New style class don't seem to support 
__delitem__:
----
class Foo(object):
   def __delitem__(self, key):
      print "__delitem__"

del Foo()[42]
----
This results in:
Traceback (most recent call last):
  File "test.py", line 5, in ?
    del Foo()[42]
TypeError: object doesn't support item deletion
----
Changing the base class to dictionary results in:
----
Traceback (most recent call last):
  File "test.py", line 5, in ?
    del Foo()[42]
KeyError: 42
----
but Foo.__delitem__ doesn't seem to be called.
