Our initial recursive implementation was made up of 5 lines of logical code and 6 lines of type definitions. All of the data was immutable and the implementation was effectively forced by the shape of the data; under these constraints it would be harder to get it wrong than to get it right.

Questions about how this could possibly be tested and maintained are unavoidable.
