There are a few implementations of 'with' out there.  The one I wrote
(which I make no guarantees about):

  http://rm-f.net/~cout/ruby/treasures/RubyTreasures-0.4/lib/hacks/with.rb.html
  http://rm-f.net/~cout/ruby/treasures/RubyTreasures-0.4/ext/hacks/kernelless_object.c.html

and another one, which appears to point to a broken link:

  http://www.ruby-lang.org/en/raa-list.rhtml?name=with-block

I think this latter one used to be implemented using instance_eval,
which can be dangerous.
