Playing around with Ruby classes and modules.

Things.rb

module Foo
  class << self
    def logger
      @logger ||= Logger.new($stdout)
    end
  end
  class FunThing
    def self.is_fun? item
      item.is_a? FunThing
    end
  end
  class LameThing
    def self.is_fun? item
      FunThing.is_fun? item
    end
    def self.log_thing
      Foo.logger.debug 'This does work, right?'
      ## How do I run the above line without explicitly calling Foo.logger?
      ## Sort of like how I can just call FunThing.is_fun? instead of Foo::FunThing.is_fun?
      # logger.debug 'This will not actually work'
    end
  end
end
fun = Foo::FunThing.new
puts Foo::FunThing.is_fun? fun
lame = Foo::LameThing.new
puts Foo::LameThing.is_fun? lame
Foo::LameThing.log_thing
