+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=83293

+ *
+ * ********************   CORRECTION !!!  *****************************
+ *
+ * When I originally wrote this test, I thought this was true:
+ * str.replace(strA, strB) == str.replace(new RegExp(strA),strB).
+ * See ECMA-262 Final Draft, 15.5.4.11 String.prototype.replace
+ *
+ * However, in http://bugzilla.mozilla.org/show_bug.cgi?id=83293
+ * Jim Ley points out the ECMA-262 Final Edition changed on this.
+ * String.prototype.replace (searchValue, replaceValue), if provided
+ * a searchValue that is not a RegExp, is NO LONGER to replace it with
+ *
+ *                  new RegExp(searchValue)
+ * but rather:
+ *                  String(searchValue)
+ *
+ * This puts the replace() method at variance with search() and match(),
+ * which continue to follow the RegExp conversion of the Final Draft.
+ * It also makes most of this testcase, as originally written, invalid.
