Hi Felix,

A method may be required explicitly:

     self subclassResponsibility

or implicity:

     self requiredMethod

where #requiredMethod has not been implemented.

You can see all of these by sending your class #requiredSelectors, for 

   MyMorph requiredSelectors asArray
   "prints: #(#addWorldHaloMenuItemsTo:hand: #slotName etc..."

Or alternativlely, if you are using the OmniBrowser you can install 
DynamicProtocols which will add a "-- required --" protocol dynamically 
when you are browsing.

The required dynamic protocol will include all the methods returned by 
#requiredSelectors. If you select one of these methods you will be shown 
a simple template for implementing the method.
