> Changes:
>
>   Added the ability to delete the item an Iterator is currently
>   indicating (Delete_Item_At (It : Iterator)). Note, this feature
>   doesn't yet work for Bags, Maps, Rings or Sets.
>
>   The C++ code offers two variants of accessors such as Queues.Front,
>   one of which returns a value while the other returns a
>   reference. The second case is now supported by generics such as eg
>   Queues.Process_Front.
>
>   The Copy operation of Collections, Queues, Rings and Stacks checks
>   for self-assignment before proceeding.
>
>   Synchronized Unbounded Rings now support blocking (balking); eg, an
>   attempt to Pop will block until the Ring has something in it to
>   pop. For related reasons, the Pop_Value operation is provided.
>
>   AVL Trees had an error (inherited from the C++) which would
>   sometimes corrupt the Tree on deletion.
>
>   Containers have new versions of the Visit and Modify generics that
>   include a parameter as an argument to Visit and Modify that is
>   passed to the Apply routine. Thanks to Steve Doiel.
>
>   Added pragma Elaborate_Body throughout.
>
>   Continued the renaming of Container parameters from Obj to something
>   slightly more mnemonic.
>
> Best wishes for 2000!
