Dynamically creating a receive PartialFunction at creation/preStart time might be a bit too fragile (in Rich's opinion). The evidence is that we—ourselves—made several errors in writing the example. Suggest getting rid of the example and maybe improving the other statically-checked example a bit more (make receive a val, make genericMessageHandler final).
