And the Ada 95 Rationale (I think that is where I read it!) points out
that distinguishing the two types leads to potential optimizations,
because whereas a general access type (ACCESS ALL) will typically be
represented as a full address, a pool-specific (Ada 83) access type
might be able to use a more compact rep, since only a specific, probably
smaller, storage pool needs to be designated.
