title: How to not repeat "obj." when invoking many methods on the same object?
body: <p>I don't remember where I saw that you can replace calls like this:</p>
  
  <pre><code>my_obj.method_1();
  my_obj.method_2();
  my_obj.method_3();
  </code></pre>
  
  <p>With something like this:</p>
  
  <pre><code>some_construct (my_obj) {
      method_1();
      method_2();
      method_3();
  }
  </code></pre>
  
  <p>Any idea on how to do this?</p>
  
  <p><em>Note: I'm not looking for method chaining</em></p>
