The Rubyists guide to Existentialism
summary
Claim: meaning arises from choice and action, demonstrated with Ruby code. Defines a tiny class Life and a class Person with attr_accessor :meaning so instance variables start nil until set. Shows the method lookup chain and how prepending a module called Society supplies a meaning getter that masks Person’s getter while Person’s setter still writes the instance variable. Builds a Religion module and uses extend on an instance to give one object a different meaning; the examples run and illustrate the point.
