Yes, I know.

You mean, the problem with having both tuple namespace and tuple class? I
never run into it yet, so can't comment.

Sure. I thought "indexed_sets" name was used because there's conceptually
more than one indexed_set in the namespace, or because more indexed_sets
are expected in future. I was wrong.

I still don't know how to avoid different name of namespace and header file
-- I believe the confusion is quite possible.
