Extension:NoViewSource.php

Legacy: This article describes a concept that has been superseded in the course of ongoing development on the Organic Design wiki. Please do not develop this any further or base work on this concept, now this page is for historic record only.

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.
