I'm sorry, I really can't agree that this helper function "solves" it. IMO, it's a workaround, not a solution. And, if I may be frank, it's a pretty ugly one. Not only that, but it still doesn't work. What if the object itself is false? -- CARL BANKS -- http://mail.python.org/mailman/listinfo/python-list
