--- Comment #4 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-10-23 21:06:09 UTC --- Ok, thanks, I wasn't there. Then please somebody add a note to that other PR. In any case, the other PR being about us actually accepting reint casts for the time being, I think it's Ok for our library to just constexpr for the time being and add a big comment about this PR, that is about the eventual need of an intrinsics as implementation detail.
