Hm, and what do you do if you have to test for Ref objects?

I didn't follow this thread thoroughly, all I can say is that I personally 
haven't missed refs in Ruby until now.  There are certainly things that 
speak in favour of your concept.

But there are also problems.  Ironically some of them seem to be caused by 
the fact that you make a Ref behave like the original instance as much as 
possible.  That way Ref usage is more implicit than explicit and this can 
lead to confusion or subtle errors due to aliasing (i.e. you think you got a 
copy of something and modify it and some other piece of code breaks because 
it was just a ref).

<soapbox>
It still might be worthwile, I just get the feeling that people try to stuff 
things from other programming languages into Ruby because they found them 
cute / useful / the only way to solve certain things in that language.  IMHO 
programming languages are different for a reason and often it's much better 
to adhere to the old saying "when in Rome do as the Romans do"... :-)
</soapbox>

Kind regards
