John, I separated the real Etoys implementation part from your email. Hopefully it helps to focus on different aspects of discussion. It took some searching, but I found a paper on the design of the guts of Squeak: ftp://st.cs.uiuc.edu/Smalltalk/Squeak/docs/OOPSLA.Squeak.html I

There's also a warning at http://wiki.squeak.org/squeak that if you want to run eToys, you need to run a different version of Squeak than everybody else. *That* is Etoys. What is wrong with it? Just out of curiosity: Exactly how is it different from vanilla squeak? (If
