bundle agent main
{
  classes:
      "classA";
      "classB";

  vars:
      "some_string" string => "cba";
      "class_expressions" slist => {"classA.classB",
                                    string(and("classA", strcmp("$(some_string)", "abc")))
      };

  reports:
      "$(class_expressions)";
}
