The difference between normal function notation and Lisp's parentheses-everywhere approach is truly office-disrupting material!
Top panel: Regular mathematical notation f(x)
is perfectly acceptable workplace banter. Bottom panel: Switch to Lisp's (f x)
prefix notation and suddenly you're getting reported to HR faster than an unhandled exception.
The real tragedy? The poor soul probably just wanted to share their excitement about discovering a language where everything is a list and parentheses are more common than semicolons in JavaScript.
