Discussion:
Addresses US-99
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.
