First off, they removed the silly rule about not having copy constructors and preferring a .Clone() member function. Praise the lawd~

Objects of copyable and movable types can be passed and returned by value, which makes APIs simpler, safer, and more general.

Second, they lifted the ban on rvalue references. One may now use rvalue refs to make movable types. They’re still banning std::forward for the time being though.

Progress!
