-// Final goal: Checker for VCL widget references. Makes sure that VCL Window subclasses are properly referenced counted and dispose()'ed.
-//
-// But at the moment it just finds subclasses of Window which are not heap-allocated
-//
-// TODO do I need to check for local and static variables, too ?
-// TODO when we have a dispose() method, verify that the dispose() methods releases all of the Window references
-// TODO when we have a dispose() method, verify that it calls the super-class dispose() method at some point.
