    Use this as:

        f = Shared(Cr(100, 3))
        g = f | f | f

    Ordinarily, you do not need to provide either a name or a scope.
    Providing a name is useful if you want a well-defined namespace
    for the variables (e.g., for saving a subnet).

    Args:
        subnet: Definition of the shared network.
        name: Optional name for the shared context.
        scope: Optional shared scope (must be a Scope, not a string).

    Raises:
        ValueError: Scope is not of type tf.Scope, name is not
        of type string, or both scope and name are given together.
