It is my understanding that Ada05 has done away with 'return-by-
reference' in favor of 'return-by-anonymous-access', which would lead
me to believe that you would *have* to use them if you want to return
an allocated limited type. Personally I am suspect of this method, as
it exposes the access value to the nefarious shenanigans other code
could potentially try (hence the original code that was testing ways
of protecting the value inside an object). Are there other ways of
doing this that aren't so...dubious?
