--- Comment #15 from Agustín Bergé <kaballo86 at hotmail dot com> --- (In reply to Jonathan Wakely from comment #14) > Agustin, do you have a copyright assignment? I do not have one. The attached <tuple> is derived from libstdc++'s <tuple> and I have left the license in place, wouldn't that be enough? I did not intend for the attachment to be a patch (it is not a patch, I did not consider coding styles, I did not run tests, etc), but merely a proof of concept implementation so that others could measure the compile-time performance win of a flat implementation.
