As discussed in the paper, there is no known implementation of the strict pointer safety facilities, which means that every use of this is a no-op, and therefore probably wrong. Pretty much the only code you can find is inside tests or a standard library: https://sourcegraph.com/search?q=context:global+declare_reachable+file:%5C.cpp+-file:en%5C.cppreference%5C.com+-file:declare_reachable%5C.pass%5C.cpp+-file:memory%5C.cpp+-file:legacy_pointer_safety%5C.cpp&patternType=standard&sm=1&groupBy=repo
