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 <nothingmuch@woobling.org> http://nothingmuch.woobling.org 0xEBD27418Thread Previous
