// In header: <boost/container/set.hpp>
template<typename InputIterator>multiset(ordered_range_t,InputIterator,InputIterator)->multiset<it_based_value_type_t<InputIterator>>;
Description
Deduction guide: allows a multiset to be constructed from an already ordered iterator range [first, last), deducing the key type from InputIterator and using the default comparator and allocator.
