--- Comment #6 from tower120 <tower120 at gmail dot com> --- Well, classical "static_asssert is not a function/variable/etc" would be enough for me. Because "there are no arguments to 'static_asssert' that depend on a template parameter" means that there IS such a function, but it does not accept current parameters set (IMHO).
