42 * Revised: 14 July 2002
44 * SUMMARY: JS should NOT error on |for(i in undefined)|, |for(i in null)|
46 * ECMA-262 3rd Edition Final spec says such statements SHOULD error. See:
48 * Section 12.6.4 The for-in Statement
49 * Section 9.9 ToObject
52 * But SpiderMonkey has decided NOT to follow this; it's a bug in the spec.
53 * See http://bugzilla.mozilla.org/show_bug.cgi?id=131348
55 * Update: Rhino has also decided not to follow the spec on this
56 * See http://bugzilla.mozilla.org/show_bug.cgi?id=136893
