- * A user adapting another type could need to overload the @c convert_to_or_fallback free function

- * The user can add the @c convert_to_or_fallback overloading on any namespace found by ADL from the @c Source or the @c Target.
- * A trick is used to overload on the return type by adding a dummy parameter having the Target.
