title: Golang JSON RawMessage literal
body: <p>Is it possible to create a json.RawMessage literal in Golang?</p>
  
  <p>I want to be able to do something like this:</p>
  
  <pre><code>type ErrorMessage struct {
      Timestamp string
      Message   json.RawMessage
  }
  
  func getTestData() ErrorMessage {
      return ErrorMessage{
          Timestamp: "test-time",
          Message:   "{}"
      }
  }
  </code></pre>
  
  <p>Or something like that. <a href="http://play.golang.org/p/C1tXFi23Bw" rel="noreferrer">This</a> is the most succinct I've seen. I have not been able to find an example of a "struct" literal for creating raw json messages.</p>
