+modernize-use-std-tie
+=====================
+
+Suggests replacing manual field-by-field lexicographical comparisons with ``std::tie``.
+
+Manual implementations of ``operator<`` and ``operator>`` can be error-prone and verbose.
+Using ``std::tie`` makes the code more readable and optimizes branch prediction.
