How about FORTRAN…because the bar is so low that pretty well everything is a Lisp 🤣

Lisp is an influentual - like smalltalk you see it’s influence in every modern programming language - but unpopular.

If you define Lisp as parenthetical syntax you can include Common Lisp and Scheme implementations, Clojure, LFE, and the Racket Lisp dialects.

Rhombus, Haskell, Elixir, Ruby, Dylan, Smalltalk, R, Julia, Rust, TCL, the ML’s, Prolog, Wolfram and Javascript are not Lisps.

All important languages that don’t need validation with a nonsensical ‘lisp’ label.
