There is a comment in elaborate-core.fun that indicates where we could add
a warning for non-unit typed expressions in sequences. The function case
above would fall out as a special case. On the down side, it means that
fully applied functions might also be warned, because one might only be
interested in their side-effects, not their results. But, a few
judiciously placed ignore applications would eliminate that.
