In my opinion __is_final would be definitely useful in general, for 4.8,
and 4.7 too, if isn't too late.
As regards the wider issue which is being discussed on the reflector -
beware, I didn't follow all the messages - 'final' disabling a nice
optimization like EBO makes me very nervous. Really, doesn't seem part
of the intended general philosophy in this area. There must be a way to
overcome the annoyance. Last resort, if suggestions like having 'final'
not forbidding private derivation cannot go through, we could imagine a
GCC attribute reverting the effect of 'final' for people (library
writers ;) knowing what they are doing. I don't know.
