--- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-04-06 07:38:39 UTC --- Hi. Not having looked into it in detail yet, your patch looks indeed reasonable. Do you have more testcases, for at lease some of the other issues you noticed? Indeed, I really meant to go again through std::tuple, I was nervous about some of those move and forward... Can you double check tuple_cat and tuple itself about that? I'm seeing some quite suspect moves, compared to the current draft. Thanks.
