        # argument is the statment handle (raw from SQLite DBD or the facade
        # from DBI), the second is how we access the @params internally held
        # variable, and the third is how these params are scrubbed before we
        # assert against them.
        #
        # the @params variable is in different spots in both statement handles
        # and the values of the params are quoted differently. However, the
        # full pipe works and I'd like to ensure that both do their job as a
        # team.
