1.10 + *
1.11 + * Date: 10 Apr 2002
1.12 + * Revised: 14 July 2002
1.13 + *
1.14 + * SUMMARY: JS should NOT error on |for(i in undefined)|, |for(i in null)|
1.15 + *
1.16 + * ECMA-262 3rd Edition Final spec says such statements SHOULD error. See:
1.17 + *
1.18 + * Section 12.6.4 The for-in Statement
1.19 + * Section 9.9 ToObject
1.20 + *
1.21 + *
1.22 + * But SpiderMonkey has decided NOT to follow this; it's a bug in the spec.
1.23 + * See http://bugzilla.mozilla.org/show_bug.cgi?id=131348
1.24 + *
1.25 + * Update: Rhino has also decided not to follow the spec on this
1.26 + * See http://bugzilla.mozilla.org/show_bug.cgi?id=136893
