   Just for completeness, Ada does have required garbage collection, but
only for a few specific types.  See A.4.5(88) for Ada.Strings.Unbounded.
(It is not possible to implement this type and the corresponding wide type
without garbage collection, although it can be done with reference
counting, and without compaction.)

   In addition, 13.11.2 allows users to implement garbage collection for a
user defined type if they wish.  I've done it and it is not that hard.
(But again, I used reference counting since circular lists were not possible.)
