I really wanted to have a feature in Ada 95 to be able to refer
to a standard access type for any given type, perhaps something
like String'Access, but I could not generate enough enthusiasm
for this idea. As a result, you do indeed tend to get junk
access all over the place.

Note that there is a String_Access type just sitting there in
unbounded strings for no apparent purpose (it is not used
anywhere in the package). Perhaps the idea is that anyone
who needs a standard string access type should with this
(rather large) package?????
