我在原型链上写了一个深度克隆对象的方法，谁能帮我完善一下吗？

Question

Object.prototype.clone = function(){
var ret = {};
var Str = Object.prototype.toString.call(this[prop]);
for(var prop in this){
if(this.hasOwnProperty(prop)){
if(Str == "[object Object]"){
ret[prop] = this[prop].clone();
}else{
ret[prop] = this[prop];
}
}
}
return ret;
}
