Instance Method Details

#included(base) ⇒ Object

“included” not “self.included” why? This module **extends other modules** it forcibly (over)writes their definitions of self.included BrighterPlanet::AutomobileTrip.extend(Emitter) -> now BrighterPlanet::AutomobileTrip has self.included MyAutomobileTrip.include(BrighterPlanet::AutomobileTrip) -> will call BrighterPlanet::AutomobileTrip.included(MyAutomobileTrip)
