   There are many OO extensions to Scheme. None, that I know, that 
   implements actors, i.e. msg exchanges with a mailbox managed as a queue 
   with a scheduler, no shared memory, asyncronous msg passing and various 
   concurrency regimes. Example (in Common  Lisp): ABCL/1 of Yonezawa 
   (Tokyo). 
   Any example in Scheme??? I'm certain to have missed it from the 
   literature ...
   It would be interesting for me to make one, but even more interestig to 
   customize/extend an existing one and reuse on it the sw we have running 
   in ABCL/1. 
   Any info ??? Tx a lot ...

I this a (strange) troll?  Scheme was apparently originally a dialect
developed by Sussman and Steele specifically to explore actors.  

At least this is *my* understanding of the genesis of Scheme[r], and
as it comes from Steele & Gabriel's "Evolution of Lisp"  I suspect it
may be accurate.
