* Date: 10 Apr 2002
* Revised: 14 July 2002
*
* SUMMARY: JS should NOT error on |for(i in undefined)|, |for(i in null)|
*
* 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
