Brain Gymnastics: Programming Language Keyword Abuse

To get to know a language a little better, this is a fun way to spend an hour. Simply try and use all the keywords of a language of choice. Then try to reduce the code to contain each keyword as few times as possible. Also, try to remove as much as possible that isn't a keyword. The code should run, and all paths should be executed. This is my Javascript snippet containing all keywords only once (except "this" which occurs twice). Only one non-keyword is used -- the variable "e". Have fun! try { do { var e; continue } while (void delete typeof null in undefined) } catch(e) { with(e) if ((function(){ for (;;) break; switch (true instanceof this){ case false: default: throw new this } return })()); else; } finally {}
