def call(command)
  # We need to raise an error here if we can't save.
  # But we only save if it's a new record.
  # Junction asserted that command was valid before calling this
  # executor, thus any errors in saving probably have to do with
  # connectivity... we want to abort.
  command.save! if command.new_record?
  # We assume that the command will catch all of its problems and
  # publish error events?
  # TODO: should wrap this up and publish a generic CommandFailedEvent.
