title: Serializing business objects as JSON
body: <p>I'm trying to serialize my business objects into JSON for consumption by a Javascript application. The problem is is that I'm trying to keep my business objects "pure" in the sense they are not aware of data access or persistence. It seems to me that "diluting" my objects with a toJSON() function would go against this goal. On the other hand, using an external object to serialize my business objects would not work since I keep all my instance variables private.</p>
  
  <p>Am I approaching this totally the wrong way?</p>
