Why do you want to do that?
>>> class WhyOhWhy(object):
... def __init__(self, f): self.f = f
... def __call__(self, *args, **kwargs): return self.f(*args,
**kwargs)
... def __eq__(self, other): return other == 0

>>> @WhyOhWhy
... def f(x): print "Why oh why,", x
...
>>> f("do this?")
Why oh why, do this?
>>> f == 0
