+/// The checker looks for constructors that can act as copy or move constructors
+/// through their forwarding reference parameters. If a non const lvalue
+/// reference is passed to the constructor, the forwarding reference parameter
+/// can be a perfect match while the const reference parameter of the copy
+/// constructor can't. The forwarding reference constructor will be called,
