No. It's still just operator(T const&). You can't use a "singular
valued" recursive_wrapper in any other operation apart from assignment, destruction or move.
How do I know if is it singular valued?
How do you know if an iterator is singular valued? You can't. Same here.
it == container.end()?
Or am I confused?
Yes, you are. That's not singular; it's a past-the-end iterator. You can still do comparisons against a past-the-end iterator, but not with a singular one. -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost
