<title>Dr. Dobb's | Generalizing Observer | September 1, 2003</title>
			<META NAME="description" CONTENT="The function facility, recently adopted by the C++ standards committee, provides a generalized way of working with arbitrary functions when all you know (or need to know) is their approximate signature. It turns out that this facility enables us to write, among other things, generalized implementations of important design patterns like Observer. Those generalized design patterns, in turn, motivate two small but important extensions to function itself.">
