Ada 95 is a very good language. IMO, it is better than any language that doesn't
have "Ada" in its name. Even Ada 83 is better than 99% of the languages in use.
The changes in later versions of the language are not difficult to pick up once
you've learned Ada 95. The major changes are

1. The data-structure library in Ada.Containers.*
2. Aspects, especially for specifying pre- and postconditions
3. Syntactic sugar to allow Object.Operation notation for tagged types
4. User-defined indexing
5. Additional for-loop forms

There is also interfaces, but "IMHO, Interfaces are worthless."--Randy Brukardt,
compiler writer, ARG member, and ARM editor.
