Comment (by danieliser):

 @MikeSchinkel, @jsphpl - That is not entirely true. In the technical
 aspect you are correct, but in execution the idea is doable.

 Though you cannot extend WP_Post you can build a custom wrapper. Check out
 this working example:

 https://github.com/danieliser/wp-oop-dev-
 modules/blob/master/Model/Post.php

 It basically uses WP_Post::instance then mimics it in an extendable way.
 Even allows post_type restriction so that an instance of Forum_Topic won't
 be initiated for a post or page.

 Beyond that we also use a factory class which is a wrapper for WP_Query
 and allows returning a custom post object via the Model\Post classes, as
 well as adding custom query args to shortcut your own query needs.

 This has actually made it so that a lot of our shortcodes can simply pass
 any WP_Query arg as a parameter, as well as the custom ones we have
 created that map to more complex query args.

 Like I said technically its not extending WP_Post, but it does everything
 expected if you could extend it via the Model\Post class.
