See my other reply. Yes for built-in objects; no for host objects, because of: # The value of the [[Class]] property of a host object may be any value, # even a value used by a built-in object for its [[Class]] property. In general I think that the internal properties of host objects are hopelessly underspecified. (That's partly why Jacaranda, ADsafe, and Cajita have to depend on no host objects being reachable from subset code.) > Step 7 of 13.2 says: > > 7.

The argument also has to depend on 15.3.4.5 steps 11c, 12, and 13. -- David-Sarah Hopwood _______________________________________________ Es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
