Hi,

Sorry for a repetition, but I've not idea there's my previous post.

So in my lib I add/remove routee to a router dynamicly(a routee represents 
a socket connection). Could be a scenario when there's no available 
ActorRef that is able to handle message. In that case I'm going to return 
an exception. 

 Unfortunately there's no way to get ActorRef from a Router(or 
Option[ActorRef]) or send it with result(like tryRoute(message: Any, 
sender: ActorRef): Boolean).

Plus current implementation just swallow messages in case of routee == 
NoRoutee

>From my point of view empty router is an exceptional situation. And 
swallowing exceptions is not a good design/practice.
