+=====================================
+
+Replace comparisons between signed and unsigned integers with their safe
+C++20 ``std::cmp_*`` alternative, if available.
+
+
+Examples of fixes created by the check:
+
+.. code-block:: c++
+
+  uint func(int a, uint b) {
+    return a == b;
+  }
+
+becomes
+
+.. code-block:: c++
+
+  #include <utility>
+
+  uint func(int a, uint b) {
+    return (std::cmp_equal(result, bla))

This is missing a semicolon at the end, and the outer parens are not actually added by the check
