"an access all type can only designate an aliased
variable and cannot designate a dynamic variable."
that's very wrong. an access all type can point to all things (why do you
think it uses all>? :-)
in particular, you can of course have a access all designate a dynamic
variable (i.e. one generated by an allocator).
one coding style that will develop in Ada 95 is simply to use all on all
access type declarations. However, I am not sure that is such a good idea,
one ought to minimize the use of aliased variables (there is a good reason
that Ada 83 did not have this feature, its overuse is definitely damaging)
