I think more that messaging was the fundamental part. Modularization and composition is pretty common in most paradigms. I actually looked this up the other day for a different comment but this is Alan Kay's own words on the subject: https://lists.squeakfoundation.org/pipermail/squeak-dev/1998-October/017019.html https://lists.squeakfoundation.org/pipermail/squeak-dev/1998... It's a concept I really like and use quite a bit in game development at the inter/intra-entity communication level even if below that I'd pick a more performant substrate.
