This is wrong.  The term "class" in Ada has a very specific meaning,
different from its use in other languages.  It was the Ada-meaning of
the term that the original poster was interested in.

It is also untrue that, in Ada, a type is implemented as a package.  In
Ada, a type is implemented as a ... type!
