title: Which light C++ event/delegate (signal/slot) library should I choose?
body: <p>I know that the <a href="https://stackoverflow.com/questions/359928/which-c-signals-slots-library-should-i-choose">question has already been asked</a> and answered, but it was more than one year ago and it looks like there are new alternatives out there.</p>
  
  <p>So I'm coding a game with the <a href="http://www.sfml-dev.org/" rel="nofollow noreferrer">SFML library</a> (which I'm starting to find pretty much cool actually) and I'm looking for a light and fast event/delegate library.</p>
  
  <p>After doing some research and having put aside the classical ones (<a href="http://www.boost.org/doc/html/signals.html" rel="nofollow noreferrer">Boosts.Signals</a>, <a href="http://libsigc.sourceforge.net/" rel="nofollow noreferrer">libsigc++</a>), I found "<a href="http://code.google.com/p/cpp-events/" rel="nofollow noreferrer">cpp-events</a>". It does not look very popular right now — since it is a very recent library — but it seems worst to be tested. I would be very interested to know if someone here tried it and can give a little feedback.</p>
  
  <p>Do you have other similar (or better) options to suggest? I look rather real projects (which will be maintained) than answers on forums.</p>
  
  <p>Thank you !</p>
