Subject: Using a class to extend a singleton?

Given:

  class X
    def yo=x; @yo=x; end
  end

  class Y
    def yo!; puts @yo; end
  end

  x = X.new

Is there any way to extend x with Y's functionality (without going
back and changing the given code)? Eg.

 >> x.yo="Hello World"
 >> x.yo!
 Hello World
