What is the advantage of using forwarding references in range-based for loops?

for (auto& e : v)
e = true;
}
This doesn't compile because rvalue vector<bool>::reference returned from the iterator won't bind to a non-const lvalue reference. But this will work:

Just wrap items you add in freshly created nodes and do not reuse those nodes - let the GC do its work.
The page on the ABA problem also provides the implementation of a lock-free stack - that actually works in .Net (&Java) with a (GC-ed) Node holding the items.)
