- * Why?
- *
- * Can be used to pass optional param by reference, and param can be std::nullopt, in which
- * case we construct a default value and use that as a reference. This is useful for passing
- * in multiple arguments as an optional structure (with default values), and there is no need to check if
- * passed structure is actually initialized.
