Quick Ruby Quiz

– 1 min read

I was talking to the Dallas Ruby group a couple of days ago, and showed them the following code:

class Fred
  class << self
    def self.say_hello
      puts "Hi!"
    end
  end
end

Someone asked whether it was possible to call the say_hello method. It is. How many ways can you find?
