First things first, thank you Wayne, Kent and Dave for your extensive and complementary explanations. As many things in python, what it seemed obscure at first now - with your help - seems perfectly obvious. Second thing: the example that Dave gave me and that I left quoted above makes use of decorators, but this is something that I still do not understand. I believe I got a grasp of the concept of metaclasses, to which the concept of decorator seems to be related, but the official documentation is a a bit obscure for me. I don't want to steal your time asking for an explanation that probably is already somewhere out there, but my google searches did not return anything useful (I assume I am using the wrong keywords here), so if you have a good pointer for me, I would be very grateful. :) Mac. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
