--- Comment #9 from Paolo Carlini <paolo.carlini at oracle dot com> ---
Martin, my point in the previous comment was simple: it's been a while since I
implemented the warning and today it finally occurred to me that I really
intended to implement a very simple warning for cast to its own type, as
consistently documented. Unfortunately the name is misleading. Personally, I
don't have any short/mid term plans to implement something much more complex
and sophisticated which goes beyond that. I'm pretty confident that will not
cause major problems to anybody because the warning isn't part of any set
enabled by default (if I'm misremembering that should definitely be changed).
Also, I would personally not object if somebody wants to deprecate the name of
the current warning, rename it to something really straightforward matching the
docs and then proceed to implement under "useless" something doing "the right
thing".
