using cloe::utility::maybe_own = typedef std::unique_ptr<T, Deleter<T> >

maybe_own is a unique_ptr that sometimes has a no-op deleter, depending on how the Deleter class is defined.

The best way to use this class is by using the C++11 initializer lists:

maybe_own<MyClass> mp;
MyClass c;
mp = {&c, false};  // not-owned
 
MyClass* cp = new MyClass();
mp = {cp, true};  // owned, c not deleted
 
mp = {new MyClass(), true};  // owned, cp now deleted
