Code to Joy
summary
Dives straight into runnable Ruby tricks: showing how aliasing to_ary to to_a lets a Struct both behave as an object and implicitly splat as multiple return values, benchmarking YAML::Store vs PStore for file persistence, turning yielders into iterables with method(:foo).to_enum and Pathname#ascend, using break with a return value to short‑circuit iteration while honoring ensure, and subclassing Module to build on‑the‑fly delegator modules via Module.new with define_method that actually works for multi‑target delegation.
