class Or(Function):
    """Implementation of logical OR (|).

    This class represents a logical OR operation that can be performed on
    two or more arguments. It supports chaining of multiple OR operations
    using the `|` operator.

    Parameters
    ----------
    *args : Any
        The arguments to be logically ORed together. At least two arguments
        are required.

    Raises
    ------
    ValueError
        If fewer than two arguments are provided.

    Examples
    --------
    >>> a = Or(Label.key == "k1", Label.key == "k2")
    >>> b = Or(Label.value == "v1", Label.value == "v2")
    >>> c = a | b

    Methods
    -------
    __or__(other)
        Supports chaining of multiple `Or` operations using the `|` operator.
