+!!!Implementation techique
+The split-splice operation is performed always for a single segment in the context of an existing segmentation; the covered range can be defined explicitly, or by partial spec. For each application of this algorithm, an instance of a //working context// is created (on stack) and initialised by scanning the existing segmentation to establish the insert point. The four stages are then performed on this working data, thereby determining the handling cases -- and in the last stage, new elements are inserted and existing elements are deleted (assuming immutable segment data, any changes and adaptations are done by inserting a modified clone copy).
