class PassRound(torch.nn.Module):
    """
    A custom torch.nn.Module that applies a soft rounding operation to the input tensor.

    Args:
        x (torch.Tensor): The input tensor to be rounded.
        y (optional): An optional secondary input, passed through unchanged.

    Returns:
        Tuple[torch.Tensor, Any]: A tuple containing the rounded tensor and the optional secondary input.

    Note:
        The actual rounding logic is implemented in `functions.PassRound.apply`.
