Here is the error message from clang: ``` <source>:13:5: error: 'decltype(auto)' in return type deduced as 'const int &' here but deduced as 'const nullopt_t' in earlier return statement 13 | return *largestElementIt; | ^ <source>:18:20: note: in instantiation of function template specialization 'findLargest<std::vector<int>>' requested here 18 | auto largest = findLargest(numbers); | ^ ```
