 What is worth noting here is that we have used @{text fast} rather than

-subgoal is nontrivial because of the nested schematic variables. For
+subgoal is non-trivial because of the nested schematic variables. For
 efficiency reasons @{text blast} does not even attempt such unifications.
 Although @{text fast} can in principle cope with complicated unification
 problems, in practice the number of unifiers arising is often prohibitive and
