[Python] `staticmethod` and `abc.abstractmethod`: Will it blend?

In my Python app I want to make a method that is both a staticmethod and an abc.abstractmethod. How do I do this?

I tried applying both decorators, but it doesn't work. If I do this:

import abc

class C(object):
__metaclass__ = abc.ABCMeta

@abc.abstractmethod
@staticmethod
def my_function(): pass


I get an exception*, and if I do this:

class C(object):
__metaclass__ = abc.ABCMeta

@staticmethod
@abc.abstractmethod
def my_function(): pass


The abstract method is not enforced.

How can I make an abstract static method?

*The exception:

File "c:\Python26\Lib\abc.py", line 29, in abstractmethod
funcobj.__isabstractmethod__ = True
AttributeError: 'staticmethod' object has no attribute '__isabstractmethod__'
