+The test case described above is correct, however the second test case in this file is not,
+'o instanceof o' should thow an exception.  According to ECMA-262:
+
+    8.6.2 Internal Properties and Methods:
+        "... only Function objects implement [[HasInstance]]"
+    11.8.6 The instanceof operator:
+        "6.If Result(4) does not have a [[HasInstance]] method, throw a TypeError exception."
+
+{} does not implement [[HasInstance]] (since it is not a function), so passing it as the
+constructor to be tested to instanceof should result in a TypeError being thrown.
