SI-6567 Warning for Option(implicitView(foo))
I've seen the reported problem before in the wild. It seems
worthy of a special warning, so long as we advocate Option.apply
as an alternative to `if (x == null) Some(x) else None`.
It is behind -Xlint at the moment, an option that could do with
some promotion.
