Class of all classes in TclOO. All classes are instances of this class (which is consequently an instance of itself!)

‣ oo::object
  ‣ oo::class

AMG: Is there a compelling reason why [oo::class new] is hidden?

AMG: Can I define a destructor for a class? Automatically deleting all subclasses, instances, and "mixees" is good, but I'm working on a project that needs some additional cleanup when a class is destroyed.
