Is extends broken/unavailable in TS 0.8.3 + ES3?

I've got a class that extends another. Very simple stuff. But when it compiles (which it does without error) it is creating the following JS which debugging tools moan about:
var __extends = this.__extends || function (d, b) {
    function __() { this.constructor = d; }
    __.prototype = b.prototype;
    d.prototype = new __();
};
The above is inserted above the JS creating my class and gives the wonderful "Uncaught TypeError: Cannot read property 'prototype' of undefined" error.

This is in TS 0.8.3 and I'm using ES3 and --out.

Is the derived class above the base class in the file? You'll need to have the derived class written after the base class.

Never mind, the issue was nothing to do with the above but to do with the way extends works.

I had a class (say classA) that extended another class (classB), and I wanted to pass a reference of classA to classB, but the second I did that it got its knickers in a twist and threw the error above. Never mind, the code was a bit hacky anyway but figured I'd post in case it catches anyone else out :)
