R.4: the original reference (T &) does not contain ownership Reason (reason)

There is no exception to this (whether in the C++ standard or in most of the code), and in fact most of the original references do not contain ownership. I want the owner to be identified so that we can reliably and efficiently delete the objects pointed to by the ownership pointer.

Example (sample)

Void f ()

{

Int& r = * new int {7}; / / bad: raw owning reference

/ /...

Delete & r; / / bad: violated the rule against deleting raw pointers

}
