+ *
+ * Date:    13 Oct 2003
+ * SUMMARY: Make our f.caller property match IE's wrt f.apply and f.call
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=222029
+ *
+ * Below, when gg calls f via |f.call|, we have this call chain:
+ *
+ *          calls                                  calls
+ *   gg() --------->  Function.prototype.call()  --------->  f()
+ *
+ *
+ * The question this bug addresses is, "What should we say |f.caller| is?"
+ *
+ * Before this fix, SpiderMonkey said it was |Function.prototype.call|.
+ * After this fix, SpiderMonkey emulates IE and says |gg| instead.
+ *
