+ * Date:    28 Feb 2002
+ * SUMMARY: Testing that Error.stack distinguishes between:
+ *
+ * A) top-level calls: myFunc();
+ * B) no-name function calls: function() { myFunc();} ()
+ *
+ * The stack frame for A) should begin with '@'
+ * The stack frame for B) should begin with '()'
+ *
+ * This behavior was coded by Brendan during his fix for bug 127136.
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=127136#c13
+ *
+ * Note: our function getStackFrames(err) orders the array of stack frames
+ * so that the 0th element will correspond to the highest frame, i.e. will
+ * correspond to a line in top-level code. The 1st element will correspond
+ * to the function that is called first, and so on...
+ *
+ * NOTE: At present Rhino does not have an Error.stack property. It is an
+ * ECMA extension, see http://bugzilla.mozilla.org/show_bug.cgi?id=123177
