  40 * SUMMARY: JS should NOT error on |for(i in undefined)|, |for(i in null)|
  41 *
  42 * ECMA-262 3rd Edition Final spec says such statements SHOULD error. See:
  43 *
  44 *               Section 12.6.4  The for-in Statement
  45 *               Section 9.9     ToObject
  46 *
  47 *
  48 * But SpiderMonkey has decided NOT to follow this; it's a bug in the spec.
  49 * See http://bugzilla.mozilla.org/show_bug.cgi?id=131348
  50 *
  51 * Update: Rhino has also decided not to follow the spec on this
  52 * See http://bugzilla.mozilla.org/show_bug.cgi?id=136893
