I'm actually writing some Emacs Lisp right now, because I want $FEATURE in Emacs. I've been away from Emacs Lisp for awhile in the land of Clojure and I'm reimporting certain things the way they are done there.
Libraries that help with that, even though the major underlying structure isn't immutable data structures make Emacs Lisp bearable are: s.el, ht.el, dash.el
It would be great if there was namespacing and less global state pollution.
Of course if you want to integrate with the rest of the Emacs ecosystem and you want some libraries that help you out make things nice means learning a whole different ballgame. Like wanting to use the great transient.el. That's super stateful and based on eieio.el. (Although transient.el is relatively good about hiding that behind a good API surface.)
Overall, even though I wish it was based on a functional core and Clojure's immutable data structure, concurrency, namespacing and its great EDN reader, I just accept the pragmatism on the human scale that if I want a great text based interface that interacts with the rest of my text driven workflow Emacs is a good choice and Emacs Lisp is acceptable.
