+    Behavior provides minimum support for all class-like objects, which define behavior
+    of other objects. Additional stuff (meta info) is found in ClassDescription and Class. 
+    Behavior provides all mechanisms needed to create instances (on the class side), 
+    and send messages to them. 
+    However, Behavior does not provide the (symbolic) information needed to compile methods 
+    for a class or to get useful information in inspectors or browsers.

+    For experts:
 
     Since instances of Behavior provide all that is needed to interact with the VM's
     message dispatch mechanism, these can be used as 'light weight' classes.
