2021-03-16 · Move semantics makes it possible for compiler to replace expensive copying operations with less expensive moves. In instead of constructing/assigning an object by a deep copy, you can do it by move constructor or move assignment operators.

Move semantics, introduced with C++11, has become a hallmark of modern C++ programming. However, it also complicates the language in many ways. Even after several years of support of move semantics experienced programmers struggle with all the details of move semantics.

Furthermore move semantics allows move-only types.
