Yes, but you were answering to MY RESPONSE and not to the original
poster. I just DIRECTLY answered the question. Other evangelizing
answers had already been given (and I didn't need to elaborate on them)
but I personally dislike the fact that these people tend to bring up
more questions INSTEAD OF solving the problem at hand. You can bring up
your own concept, fine. But please ANSWER THE QUESTION first. What
speaks against the idea that iavian just didn't get the concept of a
decorator? Nothing, since the code he already had was well capable of
solving the questions he asked without change!
