[Cuis-dev] Some un-accurate information on The Cuis Book

[Hernán Wilkinson]

About the number of classes I think it should say something like: “in the
version 5nnn the number of classes is …., that can slightly change in newer
versions”

About the scope of inst vars, they are protected in the c++/java/c#
parlance… I think the word protected should be use and reference the other
languages

Cheers
