def initialize(keys, values)
  @keys = keys

  # Field keys arrive already symbolized (Session/Transaction map the
  # RUN response fields with &:to_sym), so the map is symbol-keyed and
  # to_h returns symbol keys like the JRuby flavour. Every key in the
  # driver is stored as a symbol; retrieval by string is tolerated (#[]).
