Well, it's classmethod/staticmethod in truth, @ is the decorator

def testdec(func):
    return {"funcobj": func}

class Abc(object):
    def method():

assert isinstance(Abc.method, dict)

Basically as you can see above, @X before a function definition takes
the function, applies X, and use the result instead.

Now, naive Python level implementations of classmethod and staticmethod
would be (untested, all typed in the mailer):

def classmethod(func):
    def wrapper(self, *args, **kw):
        return func(self.__class__, *args, **kw)
    return wrapper

def staticmethod(func):
    def wrapper(self, *args, **kw):
        return func(*args, **kw)
    return wrapper
