I meant more along the lines of dynamism, s-exprs, metaprogramming, a first-class REPL, that sort of thing. Clojure is a weird lisp for sure, but it's certainly more similar to Scheme than, for instance, Java, Python, or Go (let alone Rust). Not sure what you mean by that last part, care to clarify?
Evidently, it has something to do with "a joy" to use, not with objective attributes like the details of how things work: symbols, lists, Booleans.
Also, the grandparent makes no hint of this issue at all; ravi-delia isn't responding to anything in the grandparent comment.
