Declaring class after consumption code in the same TS file will encounter TypeError.

TypeScript Version: 2.2.1 / nightly (2.2.0-dev.201xxxxx)

Code

// A *self-contained* demonstration of the problem follows...
let _object = new ObjectA();

class ObjectA {
  doNothing(): void {
  }
}

Expected behavior:
This code can run without error.

Actual behavior:
TypeError: ObjectA is not a function

Generated code:

var _object = new ObjectA();
var ObjectA = (function () {
    function ObjectA() {
    }
    ObjectA.prototype.doSomething = function () {
    };
    return ObjectA;
}());

new ObjectA() is called before ObjectA is assigned with the constructor function.
