From: Hans Mackowiak Date: 2013-03-03T18:31:31+09:00 Subject: Re: Confusion in instance method calls of super class from subclass YOU DID NOT READ WHAT I WAS WRITTEN: >> classes are instances of Class, and this is a child class of Object >> so methods defined in Object class works in other classes too its not added as a class method, but because each class is an Object, methods are defined in the Object class are callable from EACH OTHER OBJECT TOO, INCLUDING EACH OTHER CLASS OBJECT! -- Posted via http://www.ruby-forum.com/.
