Your'e right!

<code>
class Object
   def with &block
     yield self
   end
end

class Testclass < String
end

verylongobject = Testclass.new("Hakuna Matata!")

puts verylongobject.object_id

verylongobject.with do |o|
   puts o.object_id
end

o = verylongobject
puts o.object_id
</code>

It gives all the same object_id, so no copies should fly around, so 
giving it another name should be the best.
