Is there any way to reverse or undo the preventExtensions function?

It is possible to make a non extensible object extensible ?

var obj = {};
Object.preventExtensions(obj);
obj.abc = "abc"; // this line is ignored which is normal
//is there a way to make obj extensible again

How about a deep clone?

obj = JSON.parse(JSON.stringify(obj));
obj.abc = "abc"; // this line is now OK

Is OK in local code but any external references that came with obj will no longer point to the newly formed obj.
