  # This is an extremely complicated case of delegation. The method wants
  # to delegate arguments, but to have control over which keyword
  # arguments are delegated. I'm not sure the forward and backward
  # compatibility of this unusual form of delegation has really been
  # explored or there's any good way to support it. So I have done
  # done something hacky here and I'm looking at the last argument and
  # modifying the package of arguments to be delegated in-place.
