It's not a Lisp, but Haxe ( https://haxe.org/ https://haxe.org/ ) transpiles both to JS and Python. It does have a Lisp interpreter/REPL ( https://github.com/tluyben/hatch https://github.com/tluyben/hatch ) but it won't actually transpile the Lisp code itself. That being said, I think it might be difficult to find a language satisfying (2) - transpilers typically don't target readability, IME.
