Symbol to value conversion?

Is there anyway, given a Symbol, to get its value? I am adding items to a menu from an array using menu.addItem(name,i) where i is the item index in to the array. But when I get the onMenuItem(item) call, item is a Symbol rather a value of 0-n. So is the anyway to take 'item' and convert it to an integer index?

I've tried using item.toString() but it just returns "Symbol" rather than a value.

Not that I know of. What I've done is something like this...

const symbols = [
    :symbol0,
    :symbol1,
    :symbol2,
    :symbol3,
    :symbol4,
    :symbol5,
    :symbol6,
    :symbol7,
    :symbol8,
    :symbol9,
    :symbol10,
    :symbol11,
    :symbol12,
    :symbol13,
    :symbol14,
    :symbol15
    // only Menu.MAX_SIZE menu items allowed
];

class MyMenu extends Ui.Menu
{
    function initialize() {
    Menu.initialize();

    setTitle("test");

    for (var i = 0; i < 10; ++i) {
        addItem(Lang.format("Menu $1$", [ i + 1 ]), symbols[i]);
        }
    }
}

class MyMenuDelegate extends Ui.MenuInputDelegate
{
    hidden var _values;

    function initialize(values) {
        MenuInputDelegate.initialize();
        _values = values;
    }

    function onMenuItem(item) {

        for (var i = 0; i < symbols.size(); ++i) {
            if (item.equals(symbols[i])) {

                // use _values[i] to do something...

                return true;
            }
        }

        return false;
    }
}
