Why Hackers Are So Much Funnier Than You Are

Bob Nystrom is the author of the first programming language that automatically deletes your code if it doesn’t behave the way it’s supposed to. He calls his creation Vigil because it exhibits “supreme moral vigilance.”

“When a Vigil program is executed, Vigil itself will monitor all oaths,” Nystrom writes in his description of the new language. “If an oath is broken, the offending function…will be duly punished. How? Simple: it will be deleted from your source code.”
