Vampire's FiniteModelBuilder relies on the following idiom

          TermList srtT = SortHelper::getResultSort(left->term());
          unsigned srt = srtT.term()->functor();

to turn TermList sorts into unsigneds. This will potentially break for compound sorts, most notably, array sorts.

(E.g. the sort of arrays from a to b will get confused with the sort of arrays from b to c.)
