--- Comment #2 from Felix Morgner <felix.morgner at gmail dot com> --- That is why I explicitly referred to C++14. I strongly believe, that the right thing to do would be to disable it (handle it as an error) since it is just that when compiling in C++14 mode. Maybe the error message could state that this is not allowed in C++14 but as I said, in my opinion it has to be an error.
