That could be tensor.reshape, but I don't see a scenario about using it. To be honest, I don't have an answer. Bailing out the case is fine to me. If someday people think it is needed, this will help bring up the discussion. To be clear, I am not saying that this is not useful. I just don't know why this is needed.
