That is hilarious, but it will put me back to where I was fleeing from,
irb(main):001:0> o = Object.new.instance_eval do
irb(main):002:1* @a = 222
irb(main):003:1> def x
irb(main):004:2>    @a
irb(main):005:2> end
irb(main):006:1> self
irb(main):007:1> end
=> #<Object:0xb7d648c4 @a=222>
irb(main):008:0> o.x
=> 222
irb(main):014:0> o.extend Module::new {
irb(main):015:1*    def x
irb(main):016:2>       super.to_s << " is really " << @a.to_s(4)
irb(main):017:2>    end
irb(main):018:1> }
=> #<Object:0xb7d648c4 @a=222>
irb(main):019:0> o.x
=> 222
================ of course you know about this ;)

yup much food for the brain, thx for sharing.
