jt.chpl

class Fighter {
  var subclass:string;
  var level:int;
}

var mem = openmem();
var writer = mem.writer().write('{"subclass":"ninja", "level":3}');
var reader = mem.reader();

// This works
//var f = new Fighter();
//reader.readf("%jt", f);

// This doesn't
var f:Fighter;
reader.readf("%jt", f);

writeln(f);
