The Many Faces of Module
summary
Covers how Ruby modules evolve from Simula-flavored mixins into multiple concrete roles: mixins for shared behavior, module as namespace to group classes, and module function / singletons for utility APIs. Notes Ruby 2.0 adds module prepend to safely wrap existing methods (like CLOS method combination / AOP) and refinements to lexically scope monkey patches; prepend works and changes method lookup order, refinements exist but see low adoption because they require explicit enabling. Traces lineage back to 1968 concepts and Ruby’s 1993 origin.
