[Feature Request] All unhandled events

[rdrey]

Hey Paolo

I'd love to do a kind of pipe to another EventEmitter for all events that haven't been handled by my component.

The API I have in mind is the following:

server.on('foo.*', function(value1, value2) {
  console.log(this.event, value1, value2);
}).on('bar.baz', function(value1, value2) {
  console.log(this.event, value1, value2);
}).unhandled(function(value1, value2) {
  // Any event not in 'foo.*' or 'bar.baz':
  console.log(this.event, value1, value2); 
});

unhandled could be onOther or whatever else fits into the EventEmitter style.

What do you think, could this be low-level enough to be useful for everyone else?

Need this!

I'm trying to pass all events to front-end via socket.io.

ah! ok, so this is great, im considering rewriting this lib to handle plugins, where the entire wild card system would be plugged in, i've recently had some performance improvement ideas.

You can listen on "all" events using onAny, should be easy enough to make a wrapper or utility to enable this functionality. Also, adding state to the result of on doesn't seem like it'd be good for performance.
