I'm not sure whether the only place the standard doesn't require a cast is on assignment, but this is one place that the standard clearly does require a cast, and I'm all for that. Requiring a cast anywhere else the standard requires it would not offend me; although not requiring it anywhere it doesn't generate nonstandard results, and where the semantics are relatively sane, wouldn't offend me, either. -Kevin
