Ask HN: What are the current state-of-the-art Lisp implementations doing?

[sfgweilr4f]

I've seen a few lisps floating by lately and am curious in what seasoned lisp programmers think.

What are the high performance lisp implementations doing that the original didn't / simple implementations don't?

I have been writing Clojure full time since 2017. Most of my work is about building mobile/web apps and APIs.

Ferret Lang is a lisp that I dig. It compiles to C++11 and is crazy fast on low powered hardware. Coming from Clojure, Ferret feels nimble. But I don't think I'll ever have a use for it.

Thank you for sharing Ferret Lang. I'm excited to try this one out. A year ago I went on a quest for something lisp-like on the Arduino. I came across u-lisp but it seemed limited. I ultimately landed on Forth (not a lisp), which was a great learning experience. I think Ferret was what I was looking for at the time.

They are posting on HN and lambda the ultimate so they can stay relevant.

Chez and SBCL (counting the open source ones) are doing fine, and have just better compilers. SBCL optimizations are trivial to improve, Chez not so.

[contingencies]

All things considered, KIWIMOB.

Lisp is already at the pinnacle of evolution, and can easily morph into whatever it needs to. That's both its greatest strength, and its greatest weakness.
