Although the approach above is the one that I use, for the sake of 
completenes there is also this...

irb(main):001:0> module X; def x; "x"; end; end
=> nil
irb(main):002:0> class Y
irb(main):003:1> class << self
irb(main):004:2> include X
irb(main):005:2> end
irb(main):006:1> end
=> #<Class:Y>
irb(main):007:0> Y.x
=> "x"
