+* 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
