title: Modern alternative to publisher subscriber pattern
body: <p>I have a C++ Windows application. I am dealing with a publisher-subscriber situation, where one of my classes (publisher) generates data periodically and hands it off to another class (subscriber) which is constantly waiting to receive notification from the publisher. I am new to design patterns, and I looked up common implementations for publisher subscriber models, I noticed they are usually quite old, and they usually involve maintaining lists of pointers to objects. I was wondering if there is a better way of coding publisher subscriber model using C++ 11. Or using an entirely different model altogether in place of publisher - subscriber. 
  If you can name some interesting features or approaches, I will read documentation for them, write an implementation and add it here for further review.</p>
  
  <p>Update : I said I would post sample code. First, Boost Signals 2 as recommended by Jens really works great. My code is not quite different from the beginner sections on <a href="http://www.boost.org/doc/libs/1_55_0/doc/html/signals2/tutorial.html" rel="nofollow">http://www.boost.org/doc/libs/1_55_0/doc/html/signals2/tutorial.html</a></p>
