I'm not not entirely sure that I understand you correctly but I think that
you mean

    p.string() < q.string()

vs

    lexicographical_compare( p.begin(), p.end(), q.begin(), q.end() )

(equivalent to p.m_name < q.m_name).

There are two reasons to prefer lexicographical_compare. First, container
requirements. Second, consider the case where p is { "first/", "second" }
and q is { "first", "/second" }.
