+# Checks : Array element accessed by At() function without checking 
+# index is within array range.
+#
+# Reason : Whenever an element in an array is accessed, the index 
+# should be checked to ensure that it is less than array.Count(). 
+# CodeScanner checks for explicit calls to a Count() function; so 
+# if the array index is checked in a different way, it gives 
+# false positives. Accessing an invalid index can cause a panic.
