        I'm asking this because answering questions and solving problems in GitHub is what consumes most of the time.

        I end up not being able to add new features, fix bugs, review pull requests, etc. as fast as I wish because I have to spend too much time handling questions.

// The skipOffset (generally = 0) can be used to skip a given number

 * {@code GwtIncompatible}. This is more accurate for {@link Futures#catching}, which is available

 * <p>We can't use {@code PartiallyGwtIncompatible} because then the GWT compiler wouldn't recognize

 * The last point is subtle. Often the observable object will be managing its own internal state
 * using a lock, however it is dangerous to dispatch listeners while holding a lock because they
 * might run on the {@code directExecutor()} or be otherwise re-entrant (call back into your
 * object). So it is important to not call {@link #dispatch} while holding any locks. This is why
