michael@0:  * SUMMARY: JS should NOT error on |for(i in undefined)|, |for(i in null)|
michael@0:  *
michael@0:  * ECMA-262 3rd Edition Final spec says such statements SHOULD error. See:
michael@0:  *
michael@0:  *               Section 12.6.4  The for-in Statement
michael@0:  *               Section 9.9     ToObject
michael@0:  *
michael@0:  *
michael@0:  * But SpiderMonkey has decided NOT to follow this; it's a bug in the spec.
michael@0:  * See http://bugzilla.mozilla.org/show_bug.cgi?id=131348
michael@0:  *
michael@0:  * Update: Rhino has also decided not to follow the spec on this
michael@0:  * See http://bugzilla.mozilla.org/show_bug.cgi?id=136893
