8 * Date: 10 Apr 2002
9 * Revised: 14 July 2002
10 *
11 * SUMMARY: JS should NOT error on |for(i in undefined)|, |for(i in null)|
12 *
13 * ECMA-262 3rd Edition Final spec says such statements SHOULD error. See:
14 *
15 * Section 12.6.4 The for-in Statement
16 * Section 9.9 ToObject
17 *
18 *
19 * But SpiderMonkey has decided NOT to follow this; it's a bug in the spec.
20 * See http://bugzilla.mozilla.org/show_bug.cgi?id=131348
21 *
22 * Update: Rhino has also decided not to follow the spec on this
23 * See http://bugzilla.mozilla.org/show_bug.cgi?id=136893
