Greetings All, Seems the code has changed and may actually require a better fix than just the functions mentioned on this page, http://cplusplus.github.io/LWG/lwg-active.html#2899.
I am wondering if these are the functions or one of them firstly: constexpr tuple(tuple<_UElements...>&& __in) _Inherited(static_cast<_Tuple_impl<0, _UElements...>&&>(__in)) { } and why not just do all rvalue functions that are like this for all operators? Seems the spec is only mentioned a few functions but noexpect on move is normally a good idea unless the C++ standard or the C++ library needs it for other template parsing reasons. Regards, Nick
