After one month learning Clojure (a Lisp dialect running on JVM): strengths - immutable-by-default data structures eliminate entire categories of bugs, REPL-driven development enables interactive code construction, macros enable DSL creation impossible in Java. Frustrations: stack traces are unreadable (Java interop leaks), tooling ecosystem (Leiningen vs deps.edn confusion) lags behind Rust or Go. Practical: rebuilt a log parser from 200 lines in Java to 35 lines in Clojure. Performance within 10-20% of idiomatic Java. Clojure occupies a unique niche for data transformation code.
