How should I extend Injectable from another Injectable with many Injections in angular2?
<p>Is it possible to do something like this? (cause I tried, and haven't succeed):</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>@Injectable()
class A {
  constructor(private http: Http){ // &lt;-- Injection in root class
  }
  foo(){
    this.http.get()...
  };
}


@Injectable()
class B extends A{
  bar() {
    this.foo();
  }
}</code></pre>
</div>
</div>
</p>
