in HO, we have f1 l1 and f2 l2, where application is left-associative. we need to unify from the right (the outermost application is on the right) so this returns pairs to unify (including heads).
in HO, we have l1 -> ret1 and l2 -> ret2, where -> is right-associative. we need to unify from the left, so this returns pairs to unify (including return types).
