Blending Functional and OO Programming in Ruby
summary
Argues that Ruby benefits from small, immutable objects that behave like functions using the call method, and shows concrete libraries and results: Ruby ObjectMapper yields immutable functional objects, a custom pipeline composition operator composes steps, and Transflow stitches transactional steps and uses the whisper gem for publish/subscribe so controllers can pass contextual info. Demonstrates partial application/auto‑curry so loggers and persisters are reusable, reports cleaner Rails code after refactoring and fewer coupling bugs.
