Lisps have properties that are not so common in other languages: - Homoiconicity: Code and data are the same (s-expressions) - Lisp code is basically the AST in itself - It's trivial to implement lisp in lisp (eval) - Continuations (call/cc) - Macros - etc... It's a truly fascinating language. I never really did any Lisp coding outside some university projects and I still obsess and read about Scheme all the time.
