Field access operator overloading w/ cast?

3

I found a relatively easy/safe solution is to create a new abstract with the fields I want to have type safety on. It ends up looking like this:

@:access(GenericStore)
abstract Customer(GenericStore) {
    public var firstName(get,set):String;
    public var lastName(get,set):String;

    function get_firstName() {
        return Reflect.field(this.fields, "firstName");
    }
    function set_firstName(val:String) {
        Reflect.setField(this.fields, "firstName", val);
        return val;
    }

    function get_lastName() {
        return Reflect.field(this.fields, "lastName");
    }
    function set_lastName(val:String) {
        Reflect.setField(this.fields, "lastName", val);
        return val;
    }
}

Now I can do var castedCustomer = cast(customer, Customer); and it works great. The class could be built by a macro that reads in typedefs. I was hoping to see a way to layer a typedef on top of the abstract, but this works too.
