Yes. It was only a temporary solution so you wouldn't have
to mess around with the visitor.

The first visit is to read the metadata that can be determined
without the classloader/class (which up until now has been
all of it except the AOP stuff).

The second visit is once the class is resolved and the BeanInfo
is available.


  | public interface MetaDataVisitor[Node]
  | {
  |    void initialVisit(...); // the original visit(...)
  |    void describeVisit(...);
  | }
  | 

You can then do all your processing in the describe visit
knowing that context.getBeanInfo() will be available.
