I have written some code that allows to replace ivars with closures (idea stolen from Tom Christiansen's famous Tom's Object Tutorial in perl). This is much slower (about 5 to 10 !!) but might be of interest for thrade safety and the complete encapsulation (this was Tom's motivation in the famous TOT) Anyway it is quite some read ---> http://ruby-smalltalk.blogspot.com/ Cheers Robert --- Whereof one cannot speak, thereof one must be silent.
