+1 for the visitor. What would be nice is to generate methods in the
form #visit<Class Name>: for all classes in a given hierarchy (eg
Magritte's MAVisitor). The default implementation of such a method
would be to call #visit<My Super Class name>:

We have been using state machines for a long time and have built
generators for it (on a previous project, for which I do not have the
code). I still think that is a useful idea. It is difficult for the
code generator to maintain changes in the generated code with changes
in the "spec". Will you then define a DSL for the state machine?
