Hi, Indeed, DeepTraverser is the project to look at. I started it from the code of Mariano, and then Stefan Rechhart reimplemented it from scratch to make it very fast (e.g. traversing subclasses of a class is only 10% slower than the hard coded withAllSubclassesDo:) and to make it work like a stream. It's really beautiful.
