Does 'assign(to:)' produce memory leaks?

[sherlock1982]

@tgrapperon it's even easier:

extension Publisher where Self.Failure == Never {
public func assignNoRetain<Root>(to keyPath: ReferenceWritableKeyPath<Root, Self.Output>, on object: Root) -> AnyCancellable where Root: AnyObject {
    sink { [weak object] (value) in
        object?[keyPath: keyPath] = value
    }
  }
}
