Better Ruby through Functional Programming
summary
Argues that immutability and side‑effect‑free functions make Ruby code easier to reason about and scale to many cores, demonstrates an immutable Person via attr_reader and freeze the array, shows the Fibonacci as recursive example and warns about stack overflow despite Ruby 1.9.2 tailcall workarounds, and implements actor concurrency using the omnibus gem with message types RequestGreeting/Greeting (spawn loop, pattern match, reply with <<). Notes costs: extra object allocation and harder debugging for recursion.
