The next iteration of the code:

module Library

  class Main
    @@ready_to_go = false

    def Main.initialize
      puts "initializing"
      @@ready_to_go = true
    end

    def Main.do_stuff
      if not @@ready_to_go
        raise "error"
      else
        puts "doing stuff"
      end
    end

  end

  class Resource
    def Resource.meth
      Main.do_stuff
    end
  end

end

Library::Main.initialize
Library::Resource.meth

--output:--
initializing
doing stuff
