The archive concepts include an is_saving and is_loading typedef. For concrete polymorphic archive types, such as polymorphic_binary_iarchive, attempting to access these values results in a compilation error due to ambiguity - there are two accessible definitions, from different base classes, specifically detail::interface_iarchive<binary_iarchive> detail::interface_iarchive<polymorphic_iarchive>
