[New-bugs-announce] [issue20380] __defaults__ changed by *args

[Ram Rachum]

New submission from Ram Rachum:

Check the following example out. Putting *args in a function makes its __defaults__ be empty.

    Python 3.4.0b2 (v3.4.0b2:ba32913eb13e, Jan  5 2014, 16:13:26) [MSC v.1600 64 bit (AMD64)] on win32
    Type "help", "copyright", "credits" or "license" for more information.
    >>> def f(x, *args, y='meow'): pass
    ...
    >>> f.__defaults__
    >>> def g(x, y='meow'): pass
    ...
    >>> g.__defaults__
    ('meow',)
