code: public static <I, O> Function<? super Publisher<I>, ? extends Publisher<O>> lift(BiFunction<Scannable, ? super CoreSubscriber<? super O>, ? extends CoreSubscriber<? super I>> lifter) {
  		return LiftFunction.liftScannable(null, lifter);
  	}
docs: Create a function that can be used to support a custom operator via
  {@link CoreSubscriber} decoration. The function is compatible with
  {@link Flux#transform(Function)}, {@link Mono#transform(Function)},
  {@link Hooks#onEachOperator(Function)} and {@link Hooks#onLastOperator(Function)},
  but requires that the original {@link Publisher} be {@link Scannable}.
  <p>
  This variant attempts to expose the {@link Publisher} as a {@link Scannable} for
  convenience of introspection. You should however avoid instanceof checks or any
  other processing that depends on identity of the {@link Publisher}, as it might
  get hidden if {@link Scannable#isScanAvailable()} returns {@code false}.
  Use {@link #liftPublisher(BiFunction)} instead for that kind of use case.
  
  @param lifter the bifunction taking {@link Scannable} from the enclosing
  publisher (assuming it is compatible) and consuming {@link CoreSubscriber}.
  It must return a receiving {@link CoreSubscriber} that will immediately subscribe
  to the applied {@link Publisher}.
  
  @param <I> the input type
  @param <O> the output type
  
  @return a new {@link Function}
