+// ------
+// Caution: The array combinations are covered in a not entirely systematic way.
+// There are designated primitive structs that contain complete/incomplete array
+// BUT, the use of array fields has been scattered a bit randomly in an attempt to cover all
+// combinations of struct fields:
+// * ia_P
+// * a_P
+// * a_PSa
+// * aAPSa
+// * iaACS
+// * aACS
+//
+// So, a few of the possible field types are missing.
+// Additionally, it gets a little blury with the complex structs (CS) because they dont further
+// specify exactly the types of their fields
