Ah, I remember that interesting project! I just was confused by the name, "vectors" could also have meant something like optimized array processing or data-parallel computation ... Thanks for the explanation, and keep up the good work! :-)

This came from Juan Vuletich who is one of the primary people for Cuis Smalltalk. Cuis uses the same VM as Squeak but the image is different. As a result most of the discussion happens on Cuis mailing lists etc.
Juan gave a good presentation to the UK Smalltalk User's group last year and you can find the videos here.

Is there an easy answer to the question what that's good for? After some googling and searching on the mailing lists, I did not find any. :-)
