--- Comment #6 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-03-14 17:55:53 UTC --- I suspect Jon reduced the testcase a bit too much, because we have been through this kind of discussion/misunderstanding already, indeed normally we have only function *templates* in the actual code, no SFINAE to the help otherwise, agreed. Thanks Jon (and Jason) for looking into this.
