Steph,

I am trying to see where you would use? Is the below example valid of how-you would use it?

arr = [ obj1, obj2, obj3, obj4 ]
arr.each do |x|
    puts obj1.value if obj1.ann.fancy_attribute =~ /fancy_value/
end

OR

fancy_objects = 0
ObjectSpace.each_object{ |obj| fancy_objects += 1 if obj.ann.fancy_attribute =~ /fancy_value }
puts "YOu had #{fancy_object} fancy objects"

???
