// but you need to perform some sort of setup work (or store private state)
//
define(function() {
    var secretValue = "seekret";
    // do other initialization work here...
    return {
        someProp: "Oooh, how interesting!",
        tellMeSecrets: function() {
            // do interesting work
            return secretValue;
        }
    };
});
