I think the current comparison check is more clear. Also my suggestion
to move the check in a seperate function was to keep it consistent in
different places since such check can change in future and one might
change it only in one place, as it was happening during the first
iterations of this series. However I am fine to remove the function and
move the check back inline in the caller as the check is now only in two
places and it shouldn't be a big deal.
