  /**
   * A runnable to passthrough inputs unchanged or with additional keys.
   *
   *     This runnable behaves almost like the identity function, except that it
   *     can be configured to add additional keys to the output, if the input is a
   *     dict.
   *
   *     The examples below demonstrate this runnable works using a few simple
   *     chains. The chains rely on simple lambdas to make the examples easy to execute
   *     and experiment with.
