+
+I don't know why you two thought this particular container is a candidate for
+implementation via a B(+) tree. B(+) Trees are (aren't they?) for keeping *sorted* data,
+and there's no requirement in the multiway tree for the data to be in any way sorted.
+It's essentially a generalised list (as in LISP).
+
+GNAT has Ada.Containers.Red_Black_Trees (it may be an implementation-only package), which
+"declares the tree type used to implement ordered containers". A different implementation
+of the ordered containers might use B(+) Trees.
