The assignment expression seems like a vary natural way to introduce variables of limited (controlled?) scope, and the class-namespace special case doesn't seem horrible enough to put me, at least, off the idea. There will, of course, be those who abuse assignment expressions, and I'm very much looking forward to seeing what David Beazley makes of them. While Tim's expression might look (superficially) like C, the five-line alternative isn't exactly an inspiring example of Pythonicity, is it? regards Steve -------------- next part -------------- An HTML attachment was scrubbed...
