Pattern-emitter: Node event emitters with support for regular expressions

Here's a small lib I made this past weekend. I wanted to be able to listen to patterns for a specific module, but most implementations I found weren't that consistent with EventEmitter. Most had differences in behaviour when emitting events, handling exceptions, lacked support for domains, etc. So this is a quick attempt at keeping things consistent with, and inheriting from lib/events.js.

Hope this might prove to be useful!
