<C++>

* Introduction to signals and slots as used in the Qt cross-platform GUI library
from Trolltech: http://doc.trolltech.com/4.0/signalsandslots.html. This approach
makes heavy use of macro's and a code generating tool called the meta object
compiler (moc).

* Libsigc++ (http://libsigc.sourceforge.net/) is a typesafe callback framework
for C++, an alternative to the approach by Trolltech, by means of C++ template
wizzardry.

* sigslot (http://sigslot.sourceforge.net/), a light-weight alternative to
libsigc++.

* Boost.Signals (http://www.boost.org/doc/html/signals.html), an implementation
with the Boost quality stamp.


<D>

* listener.d (http://andy.tadan.us/d/listener.d), unmanaged signals using
delegates and template mixins.

* multidg.d (http://www.digitalmars.com/drn-bin/wwwnews?digitalmars.D/13297) dito.

* events.d (http://www.paperocean.org/cirrus.core.events.html) dito, but supporting funtion pointers as well (so do we).
