Ok, I better explain. At the Gang of Four trial, Ward started it and set the context about { curly bracket people, and ( round bracket people and [ square bracket people. (C++/Java, Lisp, Smalltalk for those in the know). If you knew who the people were and their historical contributions to the industry then the some of the story line was very very funny, since lots of it was insider jokes. PS no [ is NOT an array delimiter.
