I wrote the below code

    def real_decorator(function):
        '\n                                Actual    decorator    function.\n                                '
        @wraps(function)
        def wrapper(*args, **kwargs):
            '\n                                                Provides    the    actual    override    functionality    of    the    decorator.\n\n                                                Saves    the    previous    cached    value    of    the    flag    and    restores    it    (if    it\n                                                was    set),    after    overriding    it.\n\n                                                '
            waffle_namespace = flag.waffle_namespace
            namespaced_flag_name = waffle_namespace._namespaced_name(flag.flag_name)
            cached_value_existed = (namespaced_flag_name in waffle_namespace._cached_flags)
            if cached_value_existed:
                previous_value = waffle_namespace._cached_flags[namespaced_flag_name]
            waffle_namespace._cached_flags[namespaced_flag_name] = active
            with override_flag(namespaced_flag_name, active):
                function(*args, **kwargs)
            if cached_value_existed:
                waffle_namespace._cached_flags[namespaced_flag_name] = previous_value
            elif (namespaced_flag_name in waffle_namespace._cached_flags):
                del waffle_namespace._cached_flags[namespaced_flag_name]
        return wrapper
    return real_decorator

What's a good function header?
