Drupal4Hu.com: OOP and PHP or why Drupal rocks and some mistakes
On the Drupal4Hu.com site there's a recent post with a complaint about the OOP functionality in PHP and how Drupal developers should deal with its limitations.
While I was always complaining of PHP's inability of adding a method run-time, the problem we face is that you can't replace one either. So if you do what I did in the previous post, namely use the hook-alter patten (already an addition to PHP, I must say) to override the classname, that works. However, if two modules try to do this for two different methods, you fail.
He suggests to those Drupal developers out there that, for version 8 of the popular content management system, they drop the "closed crap that in PHP is called OOP" and work to make something better, implemented themselves. Something that would make it simpler for Drupal developers to create hooks into the main system for their plugins. Be sure to read the comments for other opinions on the post.
