Proto expressions are random access, but flattened views are forward-only. That's a limitation of the current implementation of the segmented Fusion stuff. It's a known problem. Segmented fusion needs a complete rewrite, but it's a metaprogramming Everest, and I'm too tired to climb it again. Some hot-shot metaprogramming wunderkind should try cutting his/her teeth on that problem. They'd earn my eternal admiration and appreciation.
Oh OK. So i may just need to *not* flatten them.
I just updated the docs to state that flatten returns a Fusion Forward Sequence. -- Eric Niebler BoostPro Computing http://www.boostpro.com
