title: import .of() for Observable in typescript
body: <p>I'm using this great repo for my angular 2 test project (TypeScript) - <a href="https://github.com/qdouble/angular-webpack2-starter" rel="noreferrer">https://github.com/qdouble/angular-webpack2-starter</a>. And I need to use <strong>Observable.of(..)</strong>. When I try to import it:</p>
  
  <pre><code>import { Observable } from "rxjs/Observable";
  import { of } from 'rxjs/observable/of';
  </code></pre>
  
  <p>I get:</p>
  
  <blockquote>
    <blockquote>
      <p>Property 'of' does not exist on type 'typeof Observable'.</p>
    </blockquote>
  </blockquote>
  
  <p>I also tried it the following way:</p>
  
  <pre><code>import { Observable } from "rxjs/Observable";
  import { of } from 'rxjs/add/observable/of'; // notice 'add'
  </code></pre>
  
  <p>I got:</p>
  
  <blockquote>
    <blockquote>
      <p>node_modules/rxjs/add/observable/of"' has no exported member 'of'.</p>
    </blockquote>
  </blockquote>
  
  <p>So, how can one import this Of() static method for Observable???</p>
