9,134 PointsConfused about the instances method
I'm having a hard time wrapping my head around pushing to the instances METHOD rather than a variable. It seems like it should be @instances.push(object) (pushing to the array itself) but instead it seems to be calling the push method on the instances method. How is this working?

11,565 PointsI have the same question too. Is it because when extending module, one cannot use the initialize method to initialize the instance variable @instances and so one have to put it in a method and use the method instead?
