Perhaps the source of confusion is that dynamic dispatching from collections
is the main new thing that Ada95 tagged types bring to the table. The other
typical facets of OOP can be accomplished in Ada83 using minor tricks. So if
you are going to use Ada95 to do things you just couldn't do Ada83, you are
typically going to be using pointers.
