//For demonstration purposes we move reverse into a separate function
//   In C++98 - this would make a deep copy then throw the original
//   In C++11 - It will detect that a temporary is passed. It uses move semantics automatically.
//   Copies the pointer and takes ownership of the buffer. 
//   Doesn't do a shallow copy or deep copy.
//   There is no need to implicitly tell the compiler what to do with a temporary data, 
//   it's error prone while the compiler knows
//   better and the case is very simple for the compiler to detect. 
//   If the user wants, he can tell it explicitly with "string&& s"
