Style question.

Given:

class OnPageChangeListener

class ViewPager {
  removeOnPageChangeListener(listener: OnPageChangeListener) { }
}

var onViewPagerPageChangeListener: OnPageChangeListener?

Which of the following would you quys prefer?

// Smart cast version

val listener = onViewPagerPageChangeListener
if (listener != null) {
  viewPager.removeOnPageChangeListener(listener)
}

// Regular let version

onViewPagerPageChangeListener?.let {
  viewPager.removeOnPageChangeListener(it)
}

// Function reference let version

onViewPagerPageChangeListener?.let(viewPager::removeOnPageChangeListener)

EDIT: Thanks for all the votes, folks! ❤️
