Retrieving name of an Object Instance

[prisma]

Is it possible to do something to the effect of

Class A extends B {

    public function A() {
        this.onRelease=this.onTrace;
    };

    public function onTrace() {
        trace(this._name);
    };
};

to get the instance name of an object. I have tried a bit with __resolve and such, but only get [object Object].

Thanks.
