data Sink m a

A Sink is a special type of Fold that does not accumulate any value, but runs only effects. A Sink has no state to maintain therefore can be a bit more efficient than a Fold with '()' as the state, especially when Sinks are composed with other operations. A Sink can be upgraded to a Fold, but a Fold cannot be converted into a Sink.
