It's very simple. The semantics you propose is move with the syntax of 
copy. Following the implicit move, the source of it is surprisingly 
modified (emptied).

That doesn't work. There is a humongous body of knowledge accumulated in 
C++ with std::auto_ptr. That artifact has been quite the show, including 
people who swore by it (!). We'd do good to simply draw from that 
experience instead of reenacting it.
