I am very much for OO design and have been brought up under the strict 
discipline of this newgroup :) However, I have seen good things used in 
bad ways. Your description of the use of event being "natural" reminds 
me of a library I just got done debugging.

Every single class in the library contained a custom wrapper for 
boost::bind, boost::asio, boost::thread, to make a "callback queue"

No class called methods on another, they were all posting callbacks to 
this queue and then handling them. It made it a son of a bitch to debug.

when I cleaned it up, it ran much faster and was much more 
maintanable...IMO anyway.


Events make sense sometimes, but not all the time. Do not be one of 
those guys that uses some pattern in every situation, even when it's not 
warranted.
