It is kind of hard to dynamically create objects whos type is determined at
run time without them.

For example I wrote a data collection application that uses an abstract
"scanner" type for data collection. When the system initializes an instance
of a class derived from scanner is created and passed to the data collection
task. The type of scanner created is selected by a user parameter.

It's kind of hard to do this without access types. So, while I agree that
access types are needed for a lot fewer cases in Ada than other languages, I
disagree with the statement that a high percentage of applications don't
need them.
