 *
 * SUMMARY: JS should error on |for(i in undefined)|, |for(i in null)|
 * See http://bugzilla.mozilla.org/show_bug.cgi?id=121744
 *
 * ECMA-262 3rd Edition Final spec says such statements should error. See:
 *
 *               Section 12.6.4  The for-in Statement
 *               Section 9.9     ToObject
 *
 *
 * BUT: SpiderMonkey has decided NOT to follow this; it's a bug in the spec.
 * See http://bugzilla.mozilla.org/show_bug.cgi?id=131348
 *
 * UPDATE: Rhino has also decided not to follow the spec on this.
 * See http://bugzilla.mozilla.org/show_bug.cgi?id=136893

 | So for now, adding an early return for this test so it won't run.  |
 |                                                                    |
