What is pod? This is a problem. I can hardly find two identical answers.   From ISO/IEC 14882: 2003 (e) p153: ... A pod-struct is an aggregate class that has no non-static data members of type non-pod-struct, Non-pod-Union (OR array of such types)

If you want to support assignment operations within a class that contains reference members, you must define the copy assignment operator yourself. And in the face of the "class containing the const member", the compiler's reaction is the same,

The smart pointer behaves like a pointer, but does not provide added functionality. For example, Item 13 explains how to use the standard auto_ptr and tr1::shared_ptr pointers to automatically delete resources on the heap at the correct time.

If the user does not provide constructors, copy constructors, copy assignment operators, and destructors, the compiler will help you create them only if they are needed. These functions generated by the compiler are public and inline.When you write
