This extension would be much like the "SELF" keyword, except that it would reference the sender of the message. In other words, SELF refers to the object that received the message, and SENDER would refer to the object that sent the message. At the time, I needed a mutual recursion between two objects, and did not like the fact that I had to pass the second object as a parameter in the message. Apple never responded to this request. Neither did Computer Language magazine, who refused to run the article I had written proposing the construct be given consideration in new OOLs. Does anyone know of a specific OOL implementation of SENDER? Any good reasons why it should not be included?
