The class template dangling is a simple wrapper around an object to indicate that the wrapped object may be dangling, that is, it refers to another object whose lifetime may have ended.
The alias template safe_iterator_t returns the iterator type of R, wrapped in dangling if the range was an rvalue range (as indicated by R not being an lvalue reference type).
They are used by range algorithms that accept rvalue ranges and return iterators into them.
