CMS build fully with OOP?

I guess you've heard of popular CMS systems like Drupal and Wordpress. Although they are great and helpful for a lot of projects, I'm wondering if they are any similar CMS systems built entirely 开发者_JAVA技巧with the new and improved OOP features. I will like to check them out. If you know any, please let me know, but please don't mention PHP frameworks...

I was using Modx Cms (http://modx.com , code is at github https://github.com/modxcms/revolution). It is entirely object-oriented, gives a lot of flexibility for the HTML and Javascript code, has a built-in templating engine; admin panel is written in ExtJS and is also customizable.
