Thanks for clarifying. At time of writing the only two data types that are routinely and consistently cast as objects in Drupal's codebase are users and nodes.

Thanks for clarifying. At time of writing the only two data types that are routinely and consistently cast as objects in Drupal's codebase are users and nodes. The comical thing is neither have methods assigned and can just as easily be cast as associative arrays (like everything else). Outside of core, contrib has gotten quite object oriented over the last few years as Views, Panels, Simpletest, Ctools (etc) are all heavily object-oriented and the popularity of these modules has driven a lot of other contrib module development that in turn is required to take an object-oriented approach to interact smoothly with these modules. Still, attempting to claim Drupal is in any way object oriented is like hot gluing a handful of feathers to a basketball and calling it a chicken.
