There are, or rather were Lisps with fewer parenthese: Lisp 2, CGOL, Dylan, but I wouldn't say they were popular. It isn't too difficult to write one yourself

There are, or rather were Lisps with fewer parenthese: Lisp 2, CGOL, Dylan, but I wouldn't say they were popular. It isn't too difficult to write one yourself. After you've done so, and used it for a while, you'll understand better why those earlier projects never gained traction, and learn to love (or, where appropriate, not notice) Lisp's parentheses.
