// Note: one thing to say: every time we use move operation we must use std::move,
// because variable is lvalue; we cannot directly bind an rvalue reference to a
// variable even if this variable is an rvalue reference. If we forgot to use
// std::move, the variable would be regarded as a lvalue and the corresponding
// copy operation would substitute move operation.(review page 533 for more details)
