Haxe ArrayAccess?

class Main {
    public var one:Int = 1;
    public function new() {
        var some = new Some(this);
        trace(some[0]);
        trace(some[1]);
    }
    public static function main() new Main();
}

class Some implements ArrayAccess<Int> {
    public var main:Main;
    public function new(m:Main) { main = m; }
    @:arrayAccess public function arrayAccess(k:Int):Int {
        return k == 1 ? main.one : -1;
    }
    @:arrayAccess public function arrayWrite(k:Int, v:Int):Int {
        return k == 1 ? main.one = v : v;
    }
}
