Well it seems to be more complicated than that, defining a visit method overrides the call to the visit(CompilationUnit n, A arg) method which contains the basic visitation logic, what that I actually need is a way of overriding specific methods (like the visit (MethodDeclaration n, A arg) and not all of them. My best guess is that I should somehow manually map the proxy methods.
