ES2015 iterator object of the generator has undefined value in watch

[life777]

Code looks ike this:

function* getFiles() {
    let urls = [].slice.call(arguments);

    let results = yield urls.map(function(url){
        return new Promise((resolve, reject) => {
            setTimeout(() => {
                resolve("new value");
            }, 1000);
        });
    });
    results.forEach((val) => { console.log(val) });
}

let iterator = getFiles("file1", "file2", "file3");
//iterator is undefined
Promise.all(iterator.next().value).then(function(results){
    iterator.next(results);
});

If I set debugger after I created an generator's iterator and place this variable into watch section (or just hover it with mouse pointer) I'll see that variable "iterator" has "undefined" value.

@life777 this is a limitation of the the node debugger protocol. Node-inspector shows the same result, right?
