+#
+# -modernize-use-trailing-return-type:
+#   Most of the times, trailing return types provide no benefit. The additional "auto" and "->" are just noise.
+#
+# -modernize-use-nodiscard:
+#   The leading [[nodiscard]] attribute adds noise to the code when reading it and may not provide considerable benefits.
+
+# Warnings are easily be overlooked when they are not treated as errors.
