The FW/1 framework includes the option of programming in the functional language Clojure which is similar in syntax to LISP. Its certainly a powerful language but Lucee dialect includes a number of functional programming capabilities increasing down the road.
How does the Lucee dialect now and in the future compare to a language like Clojure? Perhaps the main thing Clojure offers that Lucee does not is a focus on immutable data and concurrent processes allowed or made easier over that data?
Currently I just recreationally program in APL and J but will probably spend more time with Lucee and a framework for web programming. There is also a functional Java library https://www.functionaljava.org/ but my guess is Lucee dialect has a decent subset of this library so perhaps no need to use it within Lucee.
