Attaching the test program along with both versions of the
product_view<>. I used the following [bash] commands to benchmark it:

and

> do time g++-4.2 -DCOUNT=$n -DRECURSIVE test_product_view.cpp;
> done
Note that both my versions produce flattened view (a sequence of tuples
which are sequences of the same kind as the top-level sequence of the
argument). Whether the flattened or the nested representations are more
correct is, of course, a philosophical question -- but I originally
needed the flattened view for my particular application.
