I'd say the biggest area that forces me to use access types is when
dealing with complex limited types.  If I want to use any kind of container
implementation for a collection of limited types, I am forced to roll 
my own and generally have to use access types somewhere.  Same if I need
to use a limited type in non limited context.  Ada is generally very 
good about not requiring them, but there are gaps that could be filled.

You would think that a container of limited types would be very restrictive,
but with the advent of Implicit_Dereference and reference types, there
is definitely some meat there.  I would say maps and lists are the two 
areas I find the most need.
