Why example code with two variable names in for..of loop does not work? Is it so because ECMAScript 6 is still in beta mode?

Here is the code:

let arr = ['foo', 'bar', 'baz'];
    for (let [index,element] of arr.entries()) {
        console.log(index + '. ' + element);
    }

The error:

Uncaught SyntaxError: Unexpected identifier ('[', of course)
