std.json / nested key/value access?

[Robert M. Münch]

I have:

  JSONValue j = parseJSON(json_string).object;

  writeln(j); 							// works
  writeln(j["a"]); 					// works
  writeln(j["a"].object["b"]); 	// bombs

Runtime error: std.json.JSONException at std/json.d(276): JSONValue is not 
an object

How can I access a nested JSON key/value using something that comes 
close to a path notation?
