Review comment:
Since this is a syntactic modification, I am inclined to leave it as-is ..
partly because I might cause an unintentional side effect/regression and partly
because such functional utilities appear elsewhere in the Drill and Calcite
code. Ideally, if we want to move to Lambdas, we should re-visit all such
implementations.
