> Issue Type: Bug

> Using the output of the SSA parser for a logical plan, it should be possible to build an unoptimized, terribly slow reference interpreter that does drill-like things to JSON data.
> The input would be a plan in the form of a DAG which references a JSON data file on disk. Evaluation of the DAG would result in a stream of trees which could be stored back to disk for inspection or compared to reference values for testing.
