That's not exactly true. There's progress! :)

Fusion is in the review queue. Some people say that we should just
go ahead and change the old with the new. However, fusion is too
big a departure from the original tuple library. There are lots
more sequences (e.g. vector/list/set/map), an extensive set of
views), there are algorithms and iterators, etc. I'd rather regard
Fusion as an entire new library of its own. The TR1 compatibility
layer is a mere fraction of its capabilities.
