[flexcoders] Re: Deep Object Copy?

[Mike]

I just noticed the ObjectUtil.clone() method, new for Flex SDK 4.

    public static function clone(value:Object):Object
    {
        var result:Object = copy(value);
        cloneInternal(result, value);
        return result;
    }

    private static function cloneInternal(result:Object, value:Object):void
    {
        result.uid = value.uid;
        var classInfo:Object = getClassInfo(value);
        var v:Object;
        for each (var p:* in classInfo.properties) 
        {
            v = value[p];
            if (v && v.hasOwnProperty("uid")) 
                cloneInternal(result[p], v);
        }
    }

UID is discussed here: 
http://livedocs.adobe.com/flex/3/html/help.html?content=about_dataproviders_8.html

The clone() docs say "clone() differs from copy() in that the uid property of 
each object instance is retained."  Is that not true for ObjectUtil.copy() 
anyway?
