//! the important property that insertion and splicing do not invalidate iterators
//! to list elements, and that even removal invalidates only the iterators that point
//! to the elements that are removed. The ordering of iterators may be changed
//! (that is, list<T>::iterator might have a different predecessor or successor
//! after a list operation than it did before), but the iterators themselves will
//! not be invalidated or made to point to different elements unless that invalidation
//! or mutation is explicit.
