Uncaught reflect-metadata shim is required when using ES6 with Angular2 rc3
<p>I just updated Angular from <code>rc-1</code> to latest <code>rc-3</code>.
The app is using JavaScript <strong>ES6</strong> and SystemJS. When I run the app with browsersync, it works. But if I bundle the app (with systemjs-builder) and then run it, I have this error in the browser console </p>

<p>The problem comes from a component using <code>@angular/http</code> with a basic http call, if I remove <code>import {Http, HTTP_PROVIDERS} from '@angular/http' ;</code> it works.</p>

<p>Plus, it does not happen with TypeScript but it does with JS ES5 and ES6. Also it doesn't happen with Webpack.</p>

<p>I looked into the bundled code and it appears that SystemJS goes through <code>Angular</code> code before <code>Reflect</code> code... only with es6</p>

<p>index.js</p>

<pre><code>import 'reflect-metadata';
import 'es6-shim';
import 'zone.js';
import {bootstrap} from '@angular/platform-browser-dynamic';
import {App} from './app.js';
bootstrap(App);
</code></pre>

<p>app.js</p>

<pre><code>import {Component} from '@angular/core';
import {Http, HTTP_PROVIDERS} from '@angular/http';
@Component({
  selector: 'App',
  template: '',
  providers: [HTTP_PROVIDERS]
})
export class App {
  constructor(http) {}

  static get parameters() {
    return [[Http]];  
  }
}
</code></pre>
