Module Magic
summary
Walks through concrete Ruby behavior: includes put modules between class and parent, include order reverses call order (BCD prints DCB), extend opens the singleton class (extend == include into the singleton), and a single example “explains ~80% of Ruby’s method lookup.” Shows tools and patterns that actually work: const_missing autogeneration for on‑demand error classes, override bang methods to return self by redefining them in the singleton, and using drb_undumped as a tagging module. Notes included hooks can run twice and re-including a module is skipped.
