Ugh, not bit indices, at least not with *that* name!
Yes, not with that name :)
if (intersects(a,b)) // oops {
}
Maybe optional<std::size_t>?
I would rather prefer a Barton-Nackman Fallible<size_type>. I don't know if it has a place into boost, though (what about its license? is it compatible with the boost one?). Of course find_first/next, and eventually their variations, would return a Fallible<> too. Genny.
