I think we have to normalize for correctness. Consider that it may be some StopIteration subclass which set "value" on construction.
Perhaps it would be time to drop the whole delayed normalization thing, provided the benchmarks don't exhibit a slowdown? It complicates a lot of code paths.
cheers
Antoine.
