Description Patrick Mueller 2009-12-07 13:21:06 PST 
For EcmaScript 5, Object.freeze() and Object.isFrozen() are required, but not yet supported by JSC.
Comment 1 Patrick Mueller 2009-12-08 13:38:43 PST 
I believe this functionality will be relatively straight-forward to add after Object.isExtensible() / preventExtensions() is implemented.  That functionality is required for freeze() / isFrozen()'s implementation.
