+//! Class template move_iterator is an iterator adaptor with the same behavior
+//! as the underlying iterator except that its dereference operator implicitly
+//! converts the value returned by the underlying iterator's dereference operator
+//! to an rvalue reference. Some generic algorithms can be called with move
+//! iterators to replace copying with moving.
