--- Comment #17 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-10-10 11:01:59 UTC --- The patch is already in, of course. In hindsight, I think we shouldn't have bundled the SFINAE bits with addressing LWG 2141, which, I realize now, is still in flux. At least we should have discussed that. For now, I would recommend reverting the changes related to LWG 2141.
