Sigh. Yes of course. It is no uglier than walking a frame stack etc. But is it reliable? Will it work on any decorated function? If so, fine, and I'd be happy to squirrel it away as a useful standard incantation for something. If not, then it's nasty only-mostly-reliable magic and I either want little to do with it, OR I want to know its specific limitations so I know when to use it and when not. -- Cameron Simpson <c...@zip.com.au> But pessimism IS realism! - D.L.Bahr -- https://mail.python.org/mailman/listinfo/python-list
