> {{AkkaUtils.ask}} asks another actor and awaits its response. Since this constitutes
a blocking call, it might be potentially harmful when used in an actor thread. In order to
encourage developers to program asynchronously I propose to remove this helper function. That
forces the developer to handle futures explicitly.
