Chapter 9 of the above book mentioned S3 but in conjunction with S4. I
just want to understand S3 in order to understand R.oo. Although I
have created some classes in S4 before, I still have difficulties in
understanding what S3 is from the above book. Could somebody
recommended a more cleaner description of S3 without cluttered with
other irrelevant things?
