+      It is furthermore possible to make a class final. Doing this 
+      prevents a class from being specialized (it cannot be inherited 
+      by another class). There's no need to declare the methods of
+      a final class themselves as final.
+
+      Example:
+
+        <?php
+         final class Foo {
+          // class definition
+        }
+        // the next line is impossible
+        // class Bork extends Foo {}

+    * Iteration
+
+      Objects may be iterated in an overloaded way when used with
+      foreach. The default behavior is to iterate over all properties.
+
+      Example:
+
+        <?php
+            class Foo {
+                var $x = 1;
+                var $y = 2;
+            }
+
+            $obj = new Foo;
+
+            foreach ($obj as $prp_name => $prop_value) {
+                // using the property
+            }
+        ?>
+
+      TBD: Respect visibility: Show protected only when inside class
+           method and only otherwise public properties only.
+
+    * __METHOD__
+
+      The pseudo constant __METHOD__ shows the current class and method 
+      when used inside a method and the function when used outside of a 
+      class.
+
+      Example:
+
+        <?php
+            class Foo {
+                function Show() {
+                    echo __FILE__ . '(' . __LINE__ . ')' . __METHOD__;
+                }
+            }
+        ?>
+
+    * __toString()
+
+      The magic method __toString() allows to overload the object to 
+      string conversion.
+
+      Example:
+
+        <?php
+            class Foo {
+                function __toString() {
+                    return "What ever";
+            }
+
+            $obj = Foo;
+            
+            $str = (string) $obj; // call __toString()
+        ?>
+
+    * Reflection
+
+      Nearly all aspects of object oriented code can be reflected by
+      using the reflection API which is documented separatley:
+      http://sitten-polizei.de/php/reflection_api/docs/language.reflection.html
+
+      Example:
+
+        <?php
+            class Foo {
+                public $prop;
+                function Func($name) {
+                    echo "Hello $name";
+            }
+
+            reflection_class::export('Foo');
+            reflection_object::export(new Foo);
+            reflection_method::export('Foo', 'func');
+            reflection_property::export('Foo', 'prop');
+            reflection_extension::export('standard');
