i'm creating this new Smalltalk-80 vm, based a bit on the blue book, inspired by PDST and Susie, but much different in some aspects.
I talked about it some times ago here:
Now, after important refactorings, that are continuing right now, i wished to publish the project under MIT license here: http://code.google.com/p/syx.
Currently, i'm working on speed: i want a fast but complete VM as much as i can trough my very poor knowledges.
At all, i'm learning many things from this project, really... tough it's very close to Little Smalltalk's philosophy, i would like to continue my work even if it could be "yet another insignificant fork", just to learn other cool things about Smalltalk.
