I don't know. Some of his work got included anyway (some prims to  
support closures and I think
continuations) other stuff is superseded and probably a lot is  
suffering from bitrot since I don't recall hearing from him in ages.  
Are you there AJH?

I'd like to see the closures being properly supported and made  
standard, whether through his code or other code. It really is a bit  
bad to still be without them. The page http://minnow.cc.gatech.edu/ 
squeak/3717 is terribly out of date as well and Dan seems to have  
drifted off of this path. http://minnow.cc.gatech.edu/squeak/3718 is  
at least a year behind the times.
