Uncaught TypeError: $traceurRuntime.setProperty is not a function

[YonatanKra]

Hi,
I've created a simple "tag" function for a string tempalte:

var myAge = 6;
var myFormerAge = 4;

function tag(strings, ...values){
    if (values[0] < 5){
        values[1] = 'small';
    }else{
        values[1] = 'big';
    }

    return `${strings[0]}${values[0]}${strings[1]}${values[1]}`;
}

var message = tag`I am ${myAge} years old, so now I am ${""}`;
console.log(message);

But it gives me an error in console:
Uncaught TypeError: $traceurRuntime.setProperty is not a function

I'm using:
npm 2.5.1
node 0.12
traceur 0.0.90C

The code above was built to:

var myAge = 6;
var myFormerAge = 4;
function tag(strings) {
  for (var values = [],
      $__1 = 1; $__1 < arguments.length; $__1++)
    $traceurRuntime.setProperty(values, $__1 - 1, arguments[$traceurRuntime.toProperty($__1)]);
  console.log(strings);
  console.log(values);
}
var message = tag($__0, myAge, "");
console.log(message);

Which gave an error on the line with $traceurRuntime.setProperty.

setProperty was removed a while ago. What does your command look like? Maybe you are using an older version that was installed globally?
