No.  I (will) have other classes that are derived from Article that won't 
have this functionality, so I don't want it in the base class.

I think the only way I could get the code completion working would be to 
override setTitle() in NewsArticle:

/**
* Set the Title of the Article
*
* @param string $title
* @return NewsArticle
*/
public function setTitle($title = null)
{
 parent::setTitle($title);
}

That'd get old pretty fast, though.

I'm actually starting to wonder if the inheritance would work at all in a 
more strongly typed language.  I don't think Java, for example, would let 
me get away with the following:

NewsArticle newsArticle = new Article();

I might need to have a rethink this one.  Maybe it's fluent OR 
inheritance, but not both.

Thanks for your input.
