New submission from Carsten Klein <carsten.kl...@axn-software.de>:
Example
class a(frozenset):
def __init__(self, iterable):
super(a, self).__init__(iterable)
i = a([1,2,3])
> __main__:3: DeprecationWarning: object.__init__() takes no parameters
> a([1, 2, 3])
This might be due to the fact that the frozenset type structure does not
initialize the tp_init field in setobject.c, thus inheriting the original
__init__ from object.
Subclassing set will not issue that warning as it actually defines the tp_init
field to (initroc)set_init.
This holds true also for the Python 2.7 release and maybe also later releases.
Expected behaviour: do not output that warning message and provide an initproc
for the tp_field.
