-/**
- * Sometimes one wants to make an extension that defines a class that one wants
- * to backreference somewhere else in the code, doing something like:
- * <code>
- * class Extension { ... }
- * function myExtension() { new Extension; }
- * </class>
- *
- * Won't work because PHP will destroy any reference to the initialized
- * extension when the function goes out of scope, furthermore one might want to
- * use some functions in the Extension class that won't exist by the time
- * extensions get parsed which would mean lots of nasty workarounds to get
- * around initialization and reference issues.
- *
- * This class allows one to write hir extension as:
- *
- * <code>
- * function myExtension() {
- *	class Extension { ... }
- *	new PersistentObject( new Extension );
- * }
- * </code>
- *
- * The class will then not get parsed until everything is properly initialized
- * and references to it won't get destroyed meaning that it's possible to do
- * something like:
- *
- * <code>
- * $wgParser->setHook( 'tag' , array( &$this, 'tagFunc' ) );
- * </code>
- *
- * And have it work as expected
