You mean instances...
I meant something like this, which works in CPython and is a good way of
implementing the descriptor protocol :
class DecoratorClass(object):
def __init__(self, function):
self.function = function
def __call__(self, *args, **keywargs):
print 'called'
return self.function(*args, **keywargs)

@DecoratorClass
def function(*args):
print args
function('hello')
