It's possible to do some of Clojure's magic right now with my "Cloby"
library, which adds a Clojure::Object supertype you can use to get
transactional semantics for Ruby instance variables:

<code>
require 'clojure'

class MyClojureObj < Clojure::Object
  def initialize
    dosync { @foo = 'foo' }
  end

  attr_accessor :foo
end

obj = MyClojureObj.new
puts "obj.foo = " + obj.foo

begin
  puts "Setting obj.foo to 'bar'"
  obj.foo = 'bar'
rescue ConcurrencyError
  puts "Oops, need a transaction"
end

puts "Trying again with a transaction"
dosync { obj.foo = 'bar' }
puts "Success"

puts "obj.foo = " + obj.foo
</code>

This is in the "cloby" library I've never released, at
http://github.com/headius/cloby.
