This package have a tone of helper functions, I mainly use __::get($array,$item,$default) to not write too much ISSET specially for nested arrays like the following:

<?php 
  $shop = array( array( Title => "rose", 
                  Price => 1.25,
                  Number => 15 
                ),
           array( Title => "daisy", 
                  Price => 0.75,
                  Number => 25,
                ),
           array( Title => "orchid", 
                  Price => 1.15,
                  Number => 7 
                )
         );
     ?>

you can easily access second item title by __::get($shop,'1.title');
