pack_arguments is overly complex.
[ Resolved in Rapperswil by a motion to directly apply the words from the ballot comment in N3102. ]
Proposed resolution:
This issue resulted from a lack of understanding of how references are forwarded. The definition of pack_arguments should be simply:template <class... Types> tuple< ATypes &&> pack_arguments(Types&&...t);
Types: Let Ti be each type in Types....
Effects: ...
Returns:tuple< ATypes &&...>(std::forward<Types>(t)...)
The synopsis should also change to reflect this simpler signature.
