▸ pipe<M>(to, map, paused?): Subscription
Subscribes to this set's state and pipes a mapped version to a mutable subscribable set. Whenever a key added event is received through the subscription, the key will be transformed by the specified mapping function, and the transformed key will be added to the other set. Whenever a key removed event is received, the transformed key is removed from the other set if and only if no remaining key in this set maps to the same transformed key.
