Never mind . I was just trying to say that using `dict`, an adapter could be implemented (if not already there ;o) for multiple formats like the ones I mentioned above and the solution would cover many config formats ... and also I was saying that I was not sure about whether this is correct , I mean for *ANY* config formats, but definitely will work for many ;o) >> > import copy >> > self.config = copy.deepcopy(config) >> >> Why ? > > So I'm free to mutate self.config as I see fit. > why not to let the user do it if he | she thinks so. I mean if somebody supplies in a temporary mapping that can be written then why to spend that time cloning the dict ?

I was talking about `dictConfig` *FUNCTION* (to be added to logging.config ... isn't it ? ;o). I mean if dictConfig is sematically equivalent to a simple `dc.configure` why to add such function ? PS: Not a big problem anyway ;o) -- Regards, Olemis.
