Python: shortcut for writing decorators which accept arguments?

Question

Does the Python standard library have a shortcut for writing decorators which accept arguments?

For example, if I want to write a decorator like with_timeout(timeo

Answer 1

Based on Jakob's suggestion, I've implemented a small Decorator class, which I feel does a fairly decent job:

class Decorator(object):
    def __call__(self, f):
        self.f = f
        return functools.wraps(f)(lambda *a, **kw: self.wrap(*a, **kw))

    def wrap(self, *args, **kwrags):
        raise NotImplemented("Subclasses of Decorator must implement 'wrap'")

class with_timeout(Decorator):
    def __init__(self, timeout):
        self.timeout = timeout

    def wrap(self, *args, **kwargs):
        with Timeout(timeout):
            return self.f(*args, **kwargs)
