Can't resist to provide my 0.02 on the tagged/class issue, or how I present
it in my courses.
A tagged type is not a class. A tagged type is a programming construct that
can be used to build classes. This is what the building block approach is
about.
A class in the usual OOP sense is a *design pattern*, where you put a tagged
type and its associated primitive operations (the methods) in a package
specification. Ada allows you to build other design patterns, that have no
equivalent in other languages, like putting several tagged types in a single
package (a bit like friends, but not exactly similar).
