Construtores que têm um primeiro parâmetro de std::allocator_arg_t tipo deve ter um alloc segundo argumento A tipo que é um Allocator. Este alocador é usado para criar memória para quaisquer estruturas de dados internas que a function pode usar.
Original:
Constructors that have a first parameter of type std::allocator_arg_t must have a second argument alloc of type A that is an Allocator. This allocator is used to create memory for any internal data structures that the function might use.

5, 10) O F tipo deve ser CopyConstructible eo f objecto deve ser Callable. A função de objeto resultante que é criada será vazia se f é um ponteiro de função NULL, um ponteiro NULL ao membro, ou se é uma f std::function e !f == true. O f argumento é movido para o objeto função resultante.
Original:
5, 10) The type F should be CopyConstructible and the object f should be Callable. The resulting function object that is created will be empty if f is a NULL function pointer, a NULL pointer to member, or if f is a std::function and !f == true. The argument f is moved into the resulting function object.
