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