It is good to have a warning that enforces the rule of three
<a href="https://en.cppreference.com/w/cpp/language/rule_of_three">https://en.cppreference.com/w/cpp/language/rule_of_three</a>. Whenever a class has
only one or two of user-defined destructor, a user-defined copy constructor and
a user-defined copy assignment operator, Clang warns at this class.</pre>
