Extension:NoViewSource.php

From OrganicDesign

This code exhibits voodoo programming techniques. The most common of these is extending an instance's class at runtime after it has been instantiated, a technique that can be used to provide additional hooks into existing code without requiring modification of code-base files. For a list of all our scripts which exhibit voodoo, see Category:Code that uses voodoo.
