Thomas Neidhart commented on COLLECTIONS-442:
---------------------------------------------
Sorry for the delay, but most of the proposed contributions have now been
integrated in commons-collections (see the related sub-tasks).
The proposed Iter class has been re-designed for the Iterable interface (see
FluentIterable).
Most of the methods in Iter have been added, with a few exceptions: fold,
reduce -> they require additional functional interfaces. Currently it is
unclear how to proceed with the functional part in collections, especially
considering all the changes in Java 8. It would be quite easy to add them later
on if needed though.
