  # This is only present when `extras` have been merged in:
  if keyword_arguments
    # This is a little crazy. We expect the `:argument_details` extra to _include extras_,
    # but the object isn't created until _after_ extras are put together.
    # So, we have to use a special flag here to say, "at the last minute, add yourself to the keyword args."
    #
    # Otherwise:
    # - We can't access the final Arguments instance _while_ we're preparing extras
    # - After we _can_ access it, it's frozen, so we can't add anything.
    #
    # So, this flag gives us a chance to sneak it in before freezing, _and_ while we have access
    # to the new Arguments instance itself.
