Abstract objects (such as input data streams) can have more than one interesting predicate. What would testing for the "truth" of such an object mean? Clearly you would have to include a (predicate) selection operation, and that isn't notably different from just writing the boolean expression (predicate) that one has in mind. Just packaged differently.
