Is it possible to add behavior to a non-dynamic ActionScript 3 class without class inheritance?

Question

What I would like to do is something like the following:

FooClass.prototype.method = function():String
{
    return "Something";
}

var foo:FooClass = new FooClass();
foo.method();

That is, I would like to extend the generated class with one method, and not through inheritance, but through a prototype.

The class is created from WSDL, it is not a dynamic class, and I do not want to touch the generated code, because it will be overwritten anyway.

In short, I would like to have the moral equivalent of C # 3: s Extension Methods for AS3.

Edit: I accepted the answer from aib because it matches what I asked best - although with further thought it really does not solve my problem, but it’s my fault that you asked the wrong question. :) Also, upmods are for good suggestions.

footest.as:

    public class footest extends Sprite

For example, suppose you don't like the fact that Flex 3 SpriteAsset.as returns the default metrics by default [7,7,7,7] (as opposed to flex 2). To fix this, you can:

• Create a copy of SpriteAsset.as and add it to your project at /mx/core/SpriteAsset.as
• Edit the local copy to fix any problems you find.
• Run ap
