+ * `A7-1-5` - exclude auto variables initialized with an expression of non-fundamental type. Typically this occurs when using range based for loops with arrays of non-fundamental types. For example:
+   ```
+   void iterate(Foo values[]) {
+      for (auto value : values) { // COMPLIANT (previously false positive)
+         // ...
+      }
+   }
+   ```
