C std types

WebProvides a class template std::tuple, a tuple. New in C++11. Provides metaprogramming facilities working with types. Provides various utilities: class template std::pair (two-member tuples), compile-time integer sequences, helpers in constructing vocabulary types, functions such as std::move and std::forward, and many WebUsers may specialize common_type for types T1 and T2 if. std::decay is an identity transformation for both T1 and T2. If such a specialization has a member named type, it must be a public and unambiguous member type that names a cv-unqualified non-reference type to which both T1 and T2 are explicitly convertible.
