+    <title>Closures over Channels</title>
+    <para>
+     A powerful feature of parallel channels is that they allow the exchange of closures between tasks (and runtimes).
+    </para>
+    <para>
+     When a closure is sent over a channel the closure is buffered, it doesn't change the buffering of the channel transmitting the closure, 
+     but it does effect the static scope inside the closure: The same closure sent to different runtimes, or the same runtime, 
+     will not share their static scope.
+    </para>
+    <para>
+     This means that whenever a closure is executed that was transmitted by a channel, static state will be as it was when the closure was buffered.
