Detailed Description

template<typename W>
struct cxxomfort::extras::observer_ptr::observer_ptr< W >

observer_ptr - the world's dumbest smart pointer : <memory>

observer_ptr is a simple "pointer wrapper" type that manages a non-owning pointer. No further "intelligence" is added to the wrapper's behaviour. It is added to C++17 as an "experimental".
