I wonder if some unit test would be helpful ? So that we don't forget it is in the API

Though the test would basically just be a re-implementation so I agree adding it is debatable.

Thanks for this @kfastov -- really nice

@alamb
Yes, in this case, I can't think of a test that will break if API changes.
Thanks for approving, I've added the List type to the documentation comment
