RE: [flexcoders] delete class instances

Is this what you mean...?

ActionScript 3.0 does not support using the delete operator to remove an
entire object. In ActionScript 2.0, you could use delete to remove an object
or on an object property. In ActionScript 3.0, the delete operator is now
ECMAScript compatible, meaning delete can only be used on a dynamic property
of an object.
