No, because of my custom aggregation (funkystr is an artifact of that).
However, your question suggested an experiment that I may remember to try
when I get home. Of wider interest is what is passed to the lambda, which
knowledge may also be needed for other transformations and digestions.
(I may need to use 2 queries, since funkystr is still needed.)
