There is preliminary support for this, with a few limitations (no =20
call to super, access to instances variable through KVC...). A more =20
complete solution will eventually be provided.

Here is a basic example where we create a new subclass of NSObject, =20
named MyClass, with three instance variables named a, b and c, and =20
define a simple method named method1:

   > NSObject subclass:'MyClass' instanceVariableNames:'a b c'
  MyClass

   > MyClass
  MyClass

   > MyClass setFSBlock:[:self :_cmd| 'Method ' ++ _cmd ++ ' called on '
  ++ self printString] asInstanceMethod:#method1

   > myInstance :=3D MyClass alloc init

   > myInstance method1
  'Method method1 called on <MyClass: 0x4bb69c0>'

Using the setFSBlock... methods you can also add methods to existing =20
Cocoa classes.

For another approach, look at KFDecorator, from Ken Ferry at:

None that I'm aware of.

Best,
