I think you're mixing up other Lisps with Elisp. In this particular thread I'm specifically talking about Elisp, even though, in retrospect, I should've been more explicit about it and not dropped the 'E'.
AFAIK, Elisp is an interpreted language by design and always has the ability to evaluate s-expressions directly at runtime, there's no compiler-only implementation of Elisp. There's native compilation introduced in Emacs 28, but it just adds a layer of optimization, the interpreter still exists and can evaluate s-expressions directly, it doesn't turn Elisp into a "compiler-only" implementation.
But yes, there are other Lisps that compile code to machine lang, without an interpreter.
Good catch and a fine note, thank you!
- lispm 2y agoEspecially since many compiler-only implementations can evaluate Lisp code at runtime, just fine, even though they don't execute s-expressions in an Interpreter. Thus an compiler-only Lisp can be used to implement Emacs just fine. I used for many years an Emacs on top of a compiler-only Common Lisp.
