Clojure and REPL

Clojure (https://clojure.org/) is a dialect of the Lisp (https://en.wikipedia.org/wiki/Lisp_(programming_language) programming language and primarily runs on a Java virtual machine (JVM). The other target implementations include ClojureCLR (https://github.com/clojure/clojure-clr), which runs on Common Language Runtime (CLR), and ClojureScript, which compiles to JavaScript. Although Clojure uses a JVM as its underlying runtime engine, it emphasizes a functional programming language with immutability at its core. All data structures of Clojure are immutable. Since Clojure is a dialect of Lisp, it also treats code as data and is known to be homoiconic. Its syntax is built on S-expressions (https://en.wikipedia.org/wiki/S-expression) that are first parsed as a data structure and then translated into constructs of the Java programming language before...
