When the meta object protocol is exposed this will likely be a very simple meta-class mixin role. > What I'm specifically looking for would be an instance based idea, so it > doesn't permanently overwrite the class and thus consequently switch logging > on everywhere that class is used, only for > the scope of a given instance of the class. This can probably be hacked at runtime by reblessing the object into a temporarily role-mixed meta class. That said, most of the useful logging i've seen is not automatically generated. Traces are easy to do like this, but high quality logs should be hand rolled so that they convey the most meaningful representation of information. For this, aspect oriented programming can help you separate the logging from the actual body of the method, but this is not always the most "correct" behavior. -- Yuval Kogman <[EMAIL PROTECTED]> http://nothingmuch.woobling.org 0xEBD27418
