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@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?

auto json_string = `{"a": {"b": 1}}`;

Results with your code as:

{"a":{"b":1}}
{"b":1}
1

Maybe your "a" value is not an object?

Thanks, it's an array... why ever... I need to use:

	writeln(j["a"][0]["b"]);

Wasn't that obvious, because it's a big JSON structure.
