Paolo Carlini <paolo.carlini at oracle dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at gcc dot gnu.org, | |paolo.carlini at oracle dot | |com --- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-06-04 12:30:59 UTC --- Thanks Marc. I guess we need a definitive word here about whether these are c++ front issues or unavoidable problems caused by the implementation of the traits via sfinae. In the latter case we have unfortunately to be prepared to revert all the noexcept work involving traits until we get front-end support. Very sad, of course: personally, I didn't think sfinae-based techniques had serious limitations besides access-control. Would be something worth popularizing, can affect a lot of sfinae uses outside the library too, of course.
