  10 [posts](http://paul-m-jones.com/blog/?p=188) about "fluent interfaces" and
  11 I have to agree that it's a bad idea to sacrifice a reasonable
  12 API to be able to write english code.
  13
  14 It's anyway possible to accomplish that to some extent on a need-by-need basis
  15 with a class of only 20 lines of code:
  16
  17 ```php
  18 class ReturnThisDecorator
  19 {
  20     private $object;
  21     public $result;
  22
  23     function __construct($object)
  24     {
  25         if (is_object($object)) {
  26             $this->object = $object;
  27         } else {
  28             throw new InvalidArgumentException(
  29                 "Expected an object as argument"
  30             );
  31         }
  32     }
  33
  34     function __call($method, $params)
  35     {
  36         $this->result = call_user_func_array(
  37             array($this->object, $method), $params
  38         );
  39         return $this;
  40     }
  41 }
  42
  43 $sms = new ReturnThisDecorator(new SMS);
  44 echo $sms->from('...')->to('...')->message('...')->send()->result;
  45 ```
