[Flashcoders] Using an accessor for a singleton instance

[allandt bik-elliott (thefieldcomic.com)]

Does anyone know of any reason not to use an accessor in my singleton
instead of a function?

so would this work okay (bearing in mind - as2)

class com.publicis.hp.NavData
{
    private static var _instance:Data;

    public var myVar:String;

    private function Data()
    {
        trace("This class is a singleton to hold data, please use
Data.instance");
    }

    public static function get instance():Data
    {
        if (!Data._instance)
            Data._instance = new Data();

        return Data._instance;
    }
}

rather than using

public static function getInstance()

The reason i ask is that i would find it neater to use it

ie:
var myString = Data.instance.myVar;

rather than

var myString = Data.getInstance().myVar;

thanks
a
