Keep Only the Long Lines
Fan a list into a stream, drop the items that fail a predicate, then gather what survived back into a list. Two nodes carry the lesson: Collection is the fan-out — a list fed straight into a stream operator arrives as one item — and Collect is the reverse, without which an output on a stream shows only the last value that passed.
