+                                 auto nameA = A.first;
+                                 auto nameB = B.first;
+                                 int comp = nameA.compare(nameB);
+                                 if (comp)
+                                   return comp < 0;
+
+                                 auto hashA = A.second.first;
----------------
I guess you could write this as:

  return std::tie(A.first, A.second.first) < std::tie(B.first, B.second.first);

perhaps?
