https://github.com/astropy/astropy-helpers/blob/fc91b5f089a897d134d629b85e6ba57b27ed2b39/astropy_helpers/setup_helpers.py#L580-L597

    """
    A special dictionary whose default values are the empty list.
    This is useful for building up a set of arguments for
    `distutils.Extension` without worrying whether the entry is
    already present.
