There are several methods declared on OrderedCollection class. They extend the class functionality for the Inspector's new tabs purposes (and this book purposes). It would be nice to store these methods in the CodeOfSpec20Book package as extensions. Maybe that's the case, but the book doesn't say anything about it.
Some words about creation of the collection appeared only at the ending of the chapter. This is not good, not clear. It would be better to write after the First tab example something like this: #(1 1 3 2 5 2 2 1 9 3 2 2 5 7 7 8) asOrderedCollection inspect
