For example, you can use it to implement class variables that are only
accessible to instances!

     class Strange
       a = 1

       define_method(:a)   { a }
       define_method(:inc) { a += 1 }
     end

     o1 = Strange.new
     o2 = Strange.new

     puts o1.a   #=> 1
     o2.inc
     puts o1.a   #=> 2


And the scary part is that someone will find a use for this :)
