+* SUMMARY: Testing functions having duplicate formal parameter names
+*
+* SpiderMonkey was crashing on each case below if the parameters had
+* the same name. But duplicate parameter names are permitted by ECMA;
+* see ECMA-262 3rd Edition Final Section 10.1.3
+*
+* NOTE: Rhino does not have toSource() and uneval(); they are non-ECMA
+* extensions to the language. So we include a test for them at the beginning -
