The Case Of The Missing Method - A Ruby Mystery Story
summary
A concrete mystery resolution: class methods are stored on an invisible singleton class and method lookup always begins there, demonstrated by pry and ObjectSpace experiments that show creating one class yields two new live objects so ObjectSpace counts reveal surprising behavior. The talk builds a working DSL via instance_eval/DSL to scaffold city subclasses, explains when singleton classes cause hard-to-debug errors, and shows where to look when methods seem to be missing.
