+Potential Issues
+----------------
+The ``sort`` and ``stable_sort`` algorithms provided use ``std::swap`` internally instead of ``std::ranges::iter_swap``
+for swapping elements. Note that the ``std::ranges::sort`` algorithm in several C++ standard library
+implementations also does not make use of ``std::ranges::iter_swap``. The potential issue is that customizations
+targeting ``std::ranges::iter_swap`` will not be respected.
