/**
 * Challenge 1: Modify Test::$secret before it's output.
 * 
 * Rules::
 * 1. No use of Reflection API / runkit extension
 * 2. No stopping execution before Test::run()
 * 3. No Exceptions or PHP errors / warnings notices allowed
 * 4. No redefining $test
 * 
 * Hints:
 * 1. Caesar
 * 2. Magic methods
 * 3. Requires a new feature of PHP 5.4
