{
  classes:
      "none11" expression => none("jebadiah", test1);
      "none12" expression => none("2", test1);
      "none21" expression => none("jebadiah", test2);
      "none22" expression => none("2", test2);

  vars:
      "test1" slist => {
                        1,2,3,
                        "one", "two", "three",
                        "long string",
                        "four", "fix", "six",
                        "one", "two", "three",
      };


      "test2" data => parsejson('[1,2,3,
                        "one", "two", "three",
                        "long string",
                        "four", "fix", "six",
                        "one", "two", "three",]');

  reports:
      "The test1 list is $(test1)";
    none11::
      "none() test1 1 passed";
    !none11::
      "none() test1 1 failed";
    none12::
      "none() test1 2 failed";
    !none12::
      "none() test1 2 passed";

      "The test2 list is $(test2)";
    none21::
      "none() test2 1 passed";
    !none21::
      "none() test2 1 failed";
    none22::
      "none() test2 2 failed";
    !none22::
      "none() test2 2 passed";
