Subject: Adding *each*

I'm trying to wrap my head around how to do an "each" for objects of a class that I have created.

Consider this contrived example
  class X
    def initialize
      @x = [10, 'a', 'c', 9, 8]
    end
  end

In Ruby 1.8, what's the magic incantation so that I can do

  x = X.new
  x.each {|y| puts y}

I have read and reread Dave Thomas'*Programming Ruby 1.9* and ... well ...  I think I have to define *each* in class X and add some enumerable stuff ... but ... I just don't get it.
