Class template basic_const_iterator is an iterator adaptor with the same behavior as the underlying iterator except that its indirection operator implicitly converts the value returned by the underlying iterator's indirection operator to a type such that the adapted iterator is a constant iterator ([iterator.requirements]).
Some generic algorithms can be called with constant iterators to avoid mutation.
Specializations of basic_const_iterator are constant iterators.
