Summary: Instantiation init-less class with param

Initial Comment:
Instantiation new style __init__-less class with
parameters does not raise exception. Old style classes
raise TypeError: this constructor takes no arguments.

Python 2.2.2 (#37, Oct 14 2002, 17:02:34) [MSC 32 bit
(Intel)] on win32
>>> class C:
...     pass
...
>>> c = C('extra', 'params')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: this constructor takes no arguments
>>>
>>> class C(object):
...     pass
...
>>> c = C('whos','eating','my', 'params')
>>> c
<__main__.C object at 0x007A49B8>
>>>

Changed to 2.3 and bumped priority in the hopes that this
can/will be fixed for 2.3.

This is known behaviour (at least, I knew about it <wink>).

This is why:

>>> object(1,2,3)
<object object at 0x818dfb8>

I seem to recall discussion that this had to be left alone
in 2.2.X but should be fixed in 2.3...

Confirmed the behaviour in 2.2.2 and 2.3.
