Detailed Description
template<typename... Args>
struct folly::emplace_args< Args >
Argument tuple for variadic emplace/constructor calls. Stores arguments by (decayed) value. Restores original argument types with reference qualifiers and adornments at unpack time to emulate perfect forwarding.
Uses inheritance instead of a type alias to std::tuple so that emplace iterators with implicit unpacking disabled can distinguish between emplace_args and std::tuple parameters.
