title: as3 evaluate string from json as object
body: <p>I have a json object where I don't know some of the values at compile time, but I do know that all objects will be valid at runtime.  So in the example below, the first trace will output "50" and I want the second trace to output "100", the value of someObject.someparam, which gets defined at runtime. Is this possible? Thanks</p>
  
  <pre><code>var plan:Object = { "testParam": 50, "testParam2": "someObject.someParam" }
  var someObject:Object = {"someParam": 100}// this actually doesn't get defined until runtime  
  
  trace ("testParam " + plan.testParam);
  trace ("testParam2 " + someSortOfInterpreter(plan.testParam2);
  </code></pre>
