Those aren't what make a language a Lisp. There are Lisps without Automatic Memory Management, there are Lisps without restarts or images (although hot code loading is fairly common, and I've never seen a Lisp without a repl). Homoiconic expressions are an important part of it, but there are many lisps without macro systems. I'm a Schemer, and Scheme IS a lisp: we don't have restarts, but we do have call/cc, and images as Lisp has them are an optimization hack in any case. And we're finally getting some well supported implementations. Yes, we have hot code loading in most implementations. Come to the dark side, we have (lexical) cookies (encoded with the current continuation after baking, of course).
