More than one request to add functionality has been responded with "Use a
Decorator for this" or "Use a Visitor for that."

Both of these patterns assume a base class for a hierarchy of objects to be
acted upon. Does anyone realize how much harder these patterns are to
implement without an underlying interface? Wouldn't Node solve this problem?
