This over- load participates in overload resolution only if W2* is convertible to element_type*. 4-5) Implicitly declared copy and move constructors. Constructs an observer_ptr that watches other.get(). Parameters p - a pointer to an object to watch other - another observer_ptr to copy from http://cppreference.com 2022.07.31 std::experi...observer_ptr(3)
