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.
