18.11.10.2592 (December 17th 2018)

Improvements

  • library (uuid): Marked {UUID_GENERATOR}.generate_uuid as a class feature and made the code of the class SCOOP-compatible.

  • library (base): Added a new class EMPTY_ITERATION_CURSOR that can be used to implement iteration cursors for structures without any elements.
  • library (base): Added an inheritance link from CONTAINER to ITERABLE, so that all containers can be iterated over using an across loop. Most notable additions are queues, trees and files. Potential incompatibility: a descendant of a deferred container class of the library may need to implement a feature new_cursor.
