Clojure for Ruby Programmers
summary
Seven concrete claims: Clojure runs on the JVM and interoperates with Java, it offers a sequence library with lazy and infinite sequences, and it uses persistent immutable data structures that share structure and achieve practical speed via a branching factor (log base 32). The demo builds a chat app using refs/alter/dosync and a 100‑line Conway variant with a single mutable line using atoms refs agents. Macros, multimethods, metadata and warn-on-reflection tuning are shown and a substring patch is mentioned.
