I usually use decorator functions, but I think the following should work, 
too:

class deco(object):
    def __init__(self, func):
        self._func = func
    def __call__(self, *args):
        print "Decorator:", args
        self._func(*args)
    def __get__(self, *args):
        return deco(self._func.__get__(*args))
