Subject: [ruby-talk:6412] clas << a & Pascal's with <record> do...end

I was thinking that when a lot of work must be done on an object
it would be nice to alter the search path for methods without a 
receiver.

   a.do_this
   a.do_that
   a.do_the_other

could be perhaps written as:

   with a do 
      do_this
      do_that
      do_the_other
   end

However I realised you get this, pretty well, with:

   class << a
      def work_hard
         do_this
         do_that
         do_the_other
      end
   end

   a.work_hard

so I wouldn't need such a construct.  However, if I do this for many 
objects, I end up creating lots of singleton classes, that have no name.
So, to be really dynamic about this, I need to be able to destroy them
as well as create them.  Since they have no name, how can I do that?
